Q Randolph Walter Scott 1980 ABSTRACT ~

The Bell River Complex is a large layered gabbro intrusion of Archean age within the Abitibi orogenic belt. After intrusion into the Lac Watson and Wabassee volcanics it underwent regional greenschist metamorphism and was folded into an east-southeast trending anticline. Granitic and quartz dioritic plutonism separated the complex into eastern and western lobes and caused amphibolite grade metamorphism of the eastern lobe. The Bell River Complex has an intrusive relationship with the lower part of the volcanic sequence. The presence of sill-like subsidiary intrusions of the complex in the upper volcanic sequence indicates that the complex acted as a differentiation chamber for these volcanics. REE data for the upper volcanics do not eliminate this possibility, but the data could also reflect residual phases in a mantle source.

The exposed part of the Bell River Complex is mainly a medium to coarse grained metagabbro with 60-80% plagioclase and 20-40% uralitized clino-

pyroxene. A complete range of gabbros from pyroxenite to anorthosite is present along with minor dunite and peridotite. The western lobe of the complex can be divided into a felsic rich and magnetite poor lower zone about 10,000 ft. thick and an upper layered zone richer in mafics and magnetite that is about 15,000 ft. thick. In the eastern lobe of the complex this twofold division can also be recognized. Detailed field mapping and laboratory work was carried out on the transition zone between these two divisions. Cryptic variations within the cumulus plagioclase and clinopyroxene are recognized in this transition zone., The plagioclase compositions vary from Ab17 to Ah30 and the

compositions vary from pyroxene Wo48.6 En43.6 Fs7.7 to Wo 49.4 En34.8 Fs15.9 over an 8000 ft. stratigraphic interval. A small increase in the Cu/Cu+Ni ratio of the weakly mineralized pyroxenites is also recognized. The Bell River Complex has many characteristics in common with the Dore Lake Complex, and also appears to represent the upper portion of a "Bushveld" type layered intrusion.

x CHAPTER I INTRODUCTION

The Bell River complex is a layered gabbro intrusion located approximately 350 miles northwest of Montreal near Matagami, Quebec (Figure 1). The district is roughly bounded by latitudes 49°30'N and 49°55'N and by longitudes 76°45'W and 77°50'W. Matagami is easily accessible by route 61 from Amos, Quebec.

The complex consists of eastern and western lobes

separated by granitic intrusions. The current research is centered on the eastern lobe which lies about 38

miles southeast of Matagami. The area is accessible

from Matagami by float plane or helicopter.

The present research began with field work for

Canadian Occidental Petroleum Ltd. during the summer of

1976. Geological mapping of the eastern lobe was

completed on a scale of 1" = 1000' by pace and compass

traverses. A part of this area (about 1.5 miles by

4.0 miles) was also grid mapped on a scale of 1" = 400'.

During a two week period in the fall of 1977, reconnai-

ssance mapping was completed of outcrops in the western lobe of the complex along the Bell River. In addition the grid area was revisited to complete more intensive samping of several rock units.

Topography

The eastern lobe of the Bell River complex lies within the Dalhousie Hills which rise as much as 500 ft. above the surrounding area. Exposures are common near the tops of individual hills underlain by Bell River rocks, but become very rare in the surrounding granites and volcanics. The best exposed part of the grid area

(up to 15% outcrop) is in the northwest. The majority of the grid area, however, contains only a few percent of. 3

outcrop. The western lobe of the complex is very poorly

exposed. The best exposures occur at the rapids along

the Bell River.

Previous work

Previous work in the Matagami area has concentrated

on the area around the Bell River. This situation was

initially due to the easier access in that area and

later to active exploration associated with the volcano-

genic massive sulfide deposits around Matagami.

The Bell River complex has been mentioned in various.

reports on the Matagami area including Longley (1943),

Claveau (1951), Beland (1953), and Jenny (1961). The

first evaluations of the complex itself were by Freeman

(1939) and Freeman and Black (1.944). Sharpe (1968)

investigated the area around Matagami in some detail.

He provides some of the most detailed work on the western

lobe of the complex. The eastern lobe of the complex was mentioned in reports by Freeman (1939), Freeman and Black (1944) , and Claveau (1951). 4

CHAPTER II REGIONAL GEOLOGY

The Bell River Complex lies near the north central margin of the Abitibi Orogenic Belt (Figure 2). It is one of three large mafic igneous complexes within the belt which also include the Dore Lake Complex near Chibougamou, Quebec and the Kamiskotia Complex near Timmins, Ontario. Figure 3 shows the regional geology in more detail. The western lobe of the complex is seen as a 25 mi. x 10 mi. body separated from the 8 mi x 8 mi. eastern lobe by granitic intrusions. The pre-granitic strike length of the complex was at least 40 miles. Volcanic rocks to the north and south of the complex merge into one belt west of Matagami. Sedimentary rocks are intercalated with these volcanics near Matagami Lake and along the southern margin of the area. A large area of granitic rocks and migmatite occurs along the northern margin of the area. The general sequence for the area is shown in Table 1.

Volcanic Rocks

The volcanic rocks in the Matagami area have been divided into the Watson Lake and Wabassee Groups (Sharpe, 1968) . The older Watson Lake group contains mainly rhyolitic [tanin

group occurs north and south of the Watson Lake group

and continues to the east around the Bell River Complex

(Figures 3 and 4). The contact between these two volcanic units south

of the complex is marked by a thin laminated chert and

tuff horizon at the base of the Wabassee group (Sharpe,

1968). In general, however, there is an intercalation

of the two groups so that the boundary is based on

gross lithologic changes. The copper-zinc volcanogenic

massive sulfide deposits in the Matagami area (shown

in Figure 4) all occur within the stratigraphic zone

between these two volcanic groups.

Sedimentary Rocks

The sedimentary rocks occur near the top of the

Wabassee group north and south of the Bell River Complex

(see Figure 3). The 1/2 mile wide band of sediments

north of the complex consists of conglomerates,

silicified graywacke, tuff, and argillite (Auger,1922;

Longley, 1943) . The southern band of sediments, which is up to 4 miles wide, contains sericite-phyllites, argillites, greywacke,and iron formation (Freeman and

Black,1944; Beland,1953). Quartzites and conglomerates are reported in the eastern part of the belt

(Claveau, 1951). Bell River Complex The Bell River Complex is a gabbroic body which has intruded the volcanics and sediments in the Matagami area. The mineralogical and structural details on this body are discussed in Chapter 3.

Granitic Rocks The granitic rocks are some of the youngest intrusions in the area (Table 1). They cut all other rock types except for the late diabase dykes. A large granitic intrusion occurs in the southeastern part of the area (Figure 3). This intrusion continues from the Bell River, north of Matagami, east to Ramsay Bay and south to within two miles of the southern boundary of the area. Freeman (1938) named this intrusion the Olga quartz-diorite. It is medium to coarse grained and composed .of oligoclase-albite and quartz with smaller and variable amounts of microcline, biotite, hornblende, magnetite, and apatite. Other workers in the area have noted quartz monzonitic and granitic phases of this intrusion (Longley1 1943; Claveau,1951; Auger,1942). The smaller granitic bodies south of Kitchigama Lake and in the southwestern corner of Daniel Township are thought to be genetically related to the Olga quartz diorite because of lithological similarities (Longley, 1943) . 11

The granitic intrusion east and south of the eastern

lobe of the Bell River Complex is a pink granite containing 30-40o K-feldspar, 25-40o quartz, 15-20% oligoclase and 4-8% biotite (Claveau, 1951). A hornblende syenitic phase was noted as part of this study. This

granitic intrusion appears to be younger than the Olga

quartz diorite because Claveau (1951) notes it cutting and containing inclusions of the Olga body.

The small granitic intrusion on the southern rim

of Matagami Lake is called the Dunlap intrusion by

Longley (1943). He notes a gradation from diorite with Ab 50 in the southern part of the intrusion through monzonite and syenite into granite with Ab90 in the north. This distribution in rock types led Longley to

propose that this body was a differentiating intrusion

emplaced before or during the early stages of folding.

This theory would make the intrusion earlier than the

other granitic intrusions, which are post folding, and

possibly indicate an association with the Bell River

Complex. This interpretation is not entirely in agreement with the observation of Sharpe (1968) that dykes

from this body cut the Bell River Complex.

Along the northern shore of Matagami Lake a migmatite is noted by Longley (1943) and Auger (1942). It has an east-west trending, steeply dipping banding and contains amphibole, andesine, orthoclase and quartz.

This material is thought to represent completely

recrystallized volcanics and sediments. Longley states

that it has been extensively intruded by a biotite

diorite to biotite quartz diorite and later by pink

granite (probably a facies of the Olga quartz diorite)

aplite and pegmatite.

Diabase Dykes

Late gabbro dykes, which cut all other rock types, have been noted by several workers in the Matagami area.

These dykes are up to 200 ft. wide and traverse the area in a northeast direction.

The diabase is massive and has a pronounced Qphitic texture. It is composed of lathy plagioclase grains with interstitial clinopyroxene and accessory quartz and magnetite (Auger, 1942; Langley, 1943) .

Age dates

Previous workers in the Matagami area describe 'Lhe rocks as Precambrian in age. Although there are very few absolute age dates for the rocks in this area,and none on the Bell River Complex itself, some constraints on an age for the complex are possible.

One age date has been obtained from a meta-tuff approximately 20 miles east of the area shown in Figure 3 This sample comes from the eastern continuation of the

southern volcanic band. It has a hornblende K-Ar age

of 2,236+58 m.y., but Wanless et al. (1974) believe this

age represents a reheating event in the Aphebian. Therefore, no upper age limit for the intrusion of the

complex can be given. Two granitic intrusions about 17 miles south cf the area have also been dated. Lowdon et al. (1963) found a biotite K-Ar age of 2,510+125 m.y. on a 3 mile diameter quartz monzonite stock cutting volcanics and

Wanless et al. (1978) report a hornblende K-Ar age of 2,630+63 m.y. on a hornblende ademellite. If these intrusions are related to the granitic activity in the

Matagami area, these ages put a lower limit on the age for the Bell River Complex since the granitic intrusions are younger than complex.

One age date is available from a diabase dyke on the northeastern shore of Anita Bay, Matagami Lake.

Wanless et al. (1970) give a hornblende K-Ar age of

2,035+65 m.y. indicating an Aphebian age for these dykes which cut all other rock types in the area.

Structure Western Lobe

The overall structure of the western part of the Bell River Complex was poorly understood until the work associated with active exploration and mining of the Cu-

Zn deposits in the area. Sharpe (1968) used a combination of top determina-

tions on pillowed lavas and the outcrop pattern of the two volcanic groups to define a westward-plunging anticline whose axis crosses the Allard River about 3/8 mi. south of New Hosco mine (see Figure 4). This anti- clinal axis is considered to be approximately co-axial with the longitudinal axis of the complex. The southern limb of the anticline is a moderately dipping homocline with only minor subsidiary folds such as an asymetrical anticline at Mattagami Lake Mines. The volcanics to the north of the complex are steeply north and south dipping. Because of only scattered top determinations, it is thought that at least several east- west trending fold axes are present (Sharpe, 1968;

Auger,1942). Within the complex, mineralogical. layering in the marginal zones parallels the orientation of the volcanics. Since no repetition of the marginal zone lithologies is recognized within the complex, Sharpe (1968) postulates one large asymetrical anticline over the complex (Figure 5).

Two types of faulting have been recognized in the area of the western nose of the Bell River Complex.

All workers in the area have noted the development of schist zones up to 100' wide within the volcanics that parallel the fold axes. These belong to Sharpe's (1968) longitudinal faults which are thought to have developed during folding in the area. Sharpe (1968) also defines a group of transverse faults marked by clean fracture planes or narrow zones of schist or gouge. These faults have strikes between

N159W and N15°E.

Structure Eastern Lobe The structural picture in the vicinity of the eastern lobe of the Bell River Complex is not as well understood as that in the west. This situation is due to a lack of intense work in this area, the presence of granitic intrusions which have destroyed parts of the complex and surrounding volcanics, and a lack of exposures in the volcanics.

The most intensive work in the area was by Claveau (1951). He proposes at least one east-northeast trending anticline south of the complex based upon the repetition of a sedimentary unit intercalated with the volcanics. In this area the volcanics and sediments have moderate to steep dips. Top determinations are very scarce. Therefore little more can be said about the overall structure. If the anticlinorium in the western lobe continues east into this area, the simple homocline recognized to the south of the complex appears to be replaced by more complex folding.

Both transverse and longitudinal faults similar to those in the western lobe are reported in this area by Claveau (1951). He also notes the local warping of bedding schistocity in the volcanics parallel to contacts with granitic intrusions. .CHAPTER III BELL RIVER COMPLEX GEOLOGY

Western Lobe Geology The Bell River Complex has been described as a

layered gabbro-anorthosite intrusion by the previous

workers in the area. Freeman (1939) was the first to

attempt to define lithological units within the com-

plex. He concludes that the complex is a deformed

lopolith with bilaterally symetrical limbs of basal

norite which enclose a banded zone, a gneissic cata-

clastic zone and a central cataclastic zone. A later report by Freeman and Black (1944), however, does not mention these divisions.

Sharpe (1968) only investigated the western end of the complex (Figure 6). In this area he defines three divisions of the complex based upon petrographic and structural features. These divisions include marginal zones, a core zone, and apophyses and subsidiary intrusions (Figure 6). These divisions appear to be reasonable based upon the outcrops along the Bell River examined in this study. Therefore, these zones will be discussed in more detail.

Marginal Zones

The marginal zones are well layered gabbros that occur along the northern and southern margins of the .18

Western part of complex. They do not appear to continue around the western nose (Sharpe, 1968). The northern zone is about 6,000 ft. wide and has been traced for 3 miles on either side of Chenal rapids (Figure 6). The southern zone, seen in the southeastern corner of Figure 6, is about 3 miles wide and not as continuous as the northern zone. The rocks in the marginal zone are medium to coarse grained and vary from pyroxenite to anorthosite. Sharpe (1968) considers gabbroic anorthosite and anorthosite to be the most common rock types. The layering within the gabbros of the marginal zone is caused by variations in the proportion of felsic and mafic minerals in addition to changes in texture and grain. size. In general, individual layers on a scale of a few inches are rare so that individual exposures don't appear to be strikingly layered. The most common type of layering consists of bands of different rock types from several feet to several hundred feet thick. The contacts between these bands vary from sharp to gradational over a few inches to several feet. Figure 7 shows a well exposed outcrop along the Bell River that contains this type of layering. The most striking layering within the complex is 20

Figure 7 Larger scale layering within medium grained anorthosite. Eastern bank of Bell River at Chenal rapids.

Figure 8 Rhythmic layering in gabbro. Northern end of portage at Cold Spring rapids, Bell River. 21

a rhythmical layering where mafic rich bands from 2 D 4'in. thick are spaced 6 to 12 in. apart in gabbro of varying compositions. The contacts of these mafic Lands are usually gradational over about 1/4 in. Figure E shows a typical example of this type of layering from the southern marginal zone. Most of the layers, in the complex are of a symetrical type where the rock is of nearly uniform composition on each side of the median line until near the margins there is a transition to the adjacent band. However, asymetrical layering is also present where - there may be a gradual decrease in the mafic content of the rock and then suddenly an abrupt increase. This second type of layering has been called mineral graded layering by Wager and Brown (1968). A consistent top direction was not indicated by this type of layering, however. Within the northern marginal zone,Sharpe (1968) defines a crude super layering with units up to 800 ft. thick. One of these layers is very rich in magnetite and varies from 150 to 200 ft. thick. Sharpe (1968) notes that similar but less extensive magnetite rich rocks occur along the southern margin of the complex. 22

core Zone Sharpe (1968) defines the core zone as the main

part of the complex between the northern and southern marginal zones. The outcrops along the Bell River that were examined as part of this study confirm Sharpe's observations of a lack of well defined layering, a general felsic nature, and a low magnetite content for the rocks in this zone. The most common rock type is a medium to coarse grained gabbro with 60% to 80% plagioclase. Several outcrops of pegmatitic gabbro with pyroxenes up to 1 ft. long were also noted.

Apophyses and Subsidiary Intrusions Sharpe (1968) notes numerous semi-concordant gabbro intrusions in the vicinity of the western part of the Bell River Complex (Figure 6). These intrusions are thought to be subsidiary intrusions because of their spatial relationship and petrographic similarity to the complex. They are fine to medium grained and vary from intermediate gabbro to anorthosite. Sharpe (1968) also notes that some intrusions are quartz gabbro. These intrusions are sill like but they do transect the volcanics at low angles. The contacts, when observed in drill core, have a fine grained chilled 23

border (Sharpe, 1968). Sharpe notes that some of the

8î11s contain amygdales and are not easily distin- guished from massive mafic flows. The outcrops observed for this study confirm this close similarity to the massive flows north of the complex.

Eastern Lobe Geology The eastern lobe of the Bell River Complex was examined in the most detail for this study. Figure 9 shows this area in more detail. The area around the claim area, was mapped by pace and compass traverses with 1/2 mile spacings. The claim area was mapped in more detail on a cut grid with a 400 ft. line spacing. The traverse mapping in the area located a general contact on the eastern and northern sides of the complex. This contact is poorly exposed, but is characterized by a wide zone 1000 ft. wide where the number and size of the granitic dykes increases away from the complex. The contact in Figure 9 is placed where granites and complex rocks are about equally abundant. The contact of the complex with the granites in the west and the volcanics in the south was not observed because of time limitations and a lack of exposures. In these areas the contact is taken from Claveau (1951) and Freeman

d Black (1944). The eastern lobe of the complex, like the western part, contains mainly medium to coarse grained gabbro which ranges in composition from pyroxenite to anorthosite. Plagioclase feldspar and green to black amphibole are the two main constituents. The rock types in Table 2 were established for the purposes of field mapping. The classification is based on the amount of plagioclase present except in the case of the bleby anorthosite which is a textural classification. In addition to the gabbros, magnetite-ilmenite

Grid Area Geology The geology within the claim area is better understood than that in the rest of the eastern lobe because of generally better exposures and grid line mapping control. Within the grid area, individual rock types can not usually be traced from one grid line to the next. However, larger units containing predominantly mafic or felsic rich gabbro can be recognized. Five of these units are defined within the grid area (Figures 11 and 12). In general these units range from mafic rich (unit 1) to felsic rich (unit 4). Unit 5 is a large lamprophyre dyke cutting the complex.

Unit 1

Unit 1 is a fine to medium grained clinopyroxenite which has been uralitized by green to black amphibole. Up to 10% magnetite and 1-2% disseminated sulfides

(pyrrhotite, pyrite, and chalcopyrite) are often present. Outcrops usually have a rusty colour and

and exhibit gossan development. The contacts of this unit with adjacent gabbros are usually not observable, but most of the exposed areas are gradational over several feet (Figure 13).

A few fairly sharp and irregular contacts were also noted (Figure 14). Unit 1 is present as four main zones in the grid area with a total strike length of about 12,000 ft. These zones are present in the south-central, east- central, and north-central parts of the grid (Figures 11 and 12). A minor occurrence is also seen on line 88N-59E. This occurrence demonstrates that more than one pyroxenite layer occurs within the complex and provides support for the conclusion that the three main occurrences of unit 1 are not faulted segments of one zone. The unit 1 occurrences are usually between 50-100 ft. thick. Changes in the thickness of an individual zone are common. The most dramatic thickness change is seen in the north-central part of the grid where there is good outcrop control and no major dip changes. In this area the exposed width varies from less than 50 ft. to a maximum of 300 ft. At two locations (L124N - 57 + 20E and L188N -

75E and 400 ft. N) individual subangular blocks of gabbro Figure 13 Gradational contact between clinopyroxenite (top) and anorthositic gabbro. west bank of the Bell Hiver at Cold Spring rabids.

'to 2.5 ft. in diameter were observed within the pyroxenite. Their origin is not clear.

Unit 2 and 2a Unit 2 mainly consists of pyroxenitic gabbro, gabbro, and clinopyroxenite. It is present in the northwestern part of the grid (Figure 12). The most striking characteristics of this unit are a high magnetite-ilmenite content, which ranges up to 40-50% of the rock, and a well developed mineralogical layering. The sulfide mineralization in this unit is erratic. Up to 2% disseminated pyrrhotite is the most common sulfide phase. Unit 2a is a discontinuous olivine bearing zone along the eastern contact of unit 2 in the northern end of the grid. The eastern and western contacts of unit 2a are not exposed. However, the western contact at one point is only covered by a narrow 2 to 4 ft. wide zone where the contact appears to be relatively sharp and regular. Although there is not enough outcrop control to accurately define the northern and southern limits of unit 2a on line 196N, good exposures indicate that the occurrence north of line 208N does not continue 33

south to lines 208N and 204N. A detailed investigation of unit 2a north of L208N "found mainly magnetite-ilmenite dunite with minor layers up to several feet wide of magnetite-ilmenite peridotite and pyroxenite. Smaller scale layering was also noted as in Figure 15. The mineralogical layering is parallel to layering within the gabbros in the area and indicates that this unit is a layer in the complex. The available evidence indicates that this unit passes laterally into non-olivine bearing rocks via a facies change. The possibility of faulting can not be ruled out, however, because of poor outcrop control. Unit 2a is interesting because it is the only known documentation of olivine rich rocks that are part of the Bell River Complex. Sharpe (1968) notes the presence of small intrusions of peridotite at Mattagami Lake Mines (Figure 4). Another peridotite body two miles to the southwest of this occurrence at the mine has a synformal base of magnetite rich serpentinized peridotite, which grades upward into gabbro (Sharpe, 1968). The age relationship of these bodies to the Bell River complex is uncertain, however.

Jnit 3

Unit 3 has an intermediate composition and contains vainly gabbro and pyroxenitic gabbro. It is present in the southeastern and northern parts of the grid (Figures 11 and 12).

This unit is generally poorly layered, but several outcrops in the southeastern part of the grid contain nice rhythic layering similar to Figure 16. The mafic rich layers in this area contain up to 10% magnetite which is rare elsewhere in this unit.

Figure 16 Nafic rich layers in anorthositic gabbro (L188N-15E) 36

Sulfide mineralization in this unit is very erratic and at best 1-2% of the rock. Both disseminated and veinlet mineralization is present. At a few localities the sulfides were concentrated into blebs up to 1/2 in. in diameter. Pyrrhotite and pyrite are the most common sulfides along with rare chalcopyrite.

Unit 4 Unit 4 is predominantly composed of anorthositic gabbro, bleby anorthosite and feldspathic gabbro. This is the most felsic rich unit in the grid area. It is found in the southwestern, central, and northwestern parts of the property. Sulfide mineralization in this unit is similar to that in unit 3. This unit is only very rarely layered, but one outcrop in the northwestern part of the grid is particularly interesting (Figure 17). This exposure shows a wispy layering with a cross bedding relationship. Freeman and Black (1944) describe similar structures in the western lobe of the complex and Wager and Brown (1967) note similar structures in the Skaergaard. This outcrop, which is one of the few clear top indicators within the complex, indicates stratigraphic tops are to the east in this area. Figure 17 Cross beading in anortnositic gabbro. Looking east. (BL15- 22+45N) . 38

Unit 5

This unit is present near the eastern ends of lines 56N and 64N and is the only mappable non-complex material within the claim area (Figure 11). It is a fine grained, dark coloured rock containing plagioclase, hornblende and up to 1/2" diameter garnet metacrysts. No contacts with complex material were observed. Smaller dykes of unit 5 material up to 1 ft. thick and without garnet metacrysts occur in the grid area, but these are not large enough to be mappable (Figure 18). These smaller dykes have sharp and often irregular

boundaries with complex material. They typically have north to northeast strikes with average dips of 65°E. A few dykes have 100° - 124° strikes and 40° - 80° dips 'to the southwest. All of these dykes were originally mapped as fine grained gabbro, but they are now thought to be lamprophyre dykes. Claveau (1951) notes similar dykes cut by granite pegmatites. He suspects that the lamprophyres are older than the large granitic intrusions since they were not seen in those areas. The presence of garnet metacrysts in the unit 5 material supports an older age than the granites (Chapter VI). In several places the lamprophyre dykes appear to have been intruded into fault zones because of different complex rock types on either contact. Many dykes often have a pronounced schistocity parallel to the contacts indicating fault movement after intrusion.

Granitic Dykes Numerous quartz diorite and granite dykes were observed within the grid area. These dykes are typically 1/2 to 6 in. thick, but several in the northern part of the grid are up to 50 ft. wide. Because of their small size and discontinuous nature they are not shown in 40

es 11 and 12. These dykes are medium to coarse grained and lack

`chilled border facies. The contacts with complex t material are sharp and show little alteration effects.

Since the majority of the dykes are quartz diorites, they appear to be part of the Olga quartz diorite. The less numerous granite dykes probably originated from the pink granite to the east of the complex.

Structure within the Eastern Lobe The gabbros within the eastern lobe of the Bell River Complex generally have north-northeast strikes and an average 70° dip to the southeast (Figures 9,

11 and 12). Local deviations are common resulting in east-west strikes and usually steep dips. These devia-

tions could represent local folding and/or faulting, but the exact cause could not be determined because marker horizons are not present.

The gabbros locally exhibit a foliation produced by the orientation of the amphiboles and chlorite. Two foliation directions are noted. The dominant direction has a northeast strike and an average 65° dip to the southeast. This direction is nearly parallel to the layering and is probably related to the folding of the complex. The minor foliation, which was only noted 41

thin the grid area, has a northwest strike and moderate steep dip to the southwest. Faulting within the grid area was indicated when field attempts were made to trace unit 1 between grid lines. Because of limited exposures, however, the faulting was only observed in this unit on line 16N where a 65° steeply dipping fault has a few feet of offset. When attempts were made to connect rock units from one grid line to another, particularly within the northern half of the property, faulting was also indicated from a combination of strike data, magnetometer data, and exposures. Several fault orientations were attempted, but the simplest interpretation resulted in a nearly east-west strike. This direction is supported by several minor faults within the grid area with 115°/?, 90°/78°S, 140°/? , and 80°/61°S orientations. These faults have offsets from a few inches to 20 ft. An east- west faulting direction is also supported by the minor foliation and minor stream valleys in the grid area. The east-west striking fault just north of line 188N is indicated by a persistent cliff and the linear stream channel cutting through that area. A series of faults with N40E strikes is also 42

icated on the geologic map of the grid area (Figures 11 and 12). These faults are inferred from the major northeast trending stream valleys and the major foliation which parallel this direction. 43

MUTER Iv MAGNETOMETRY

Regional Magnetometry Figure 19 is a regional aeromagnetic map of the Matagami area showing the outline of the Bell River Complex. Several distinctive magnetic anomalies are present., The northern margin of the complex is characterized by strong magnetic anomalies that are abruptly terminated in the vicinity of Olga Lake by the Olga quartz diorite intrusion. A weaker and less well developed anomalous area is also present along the southern margin of the complex. This zone is also truncated in the east by the Olga intrusion, but it reappears along the southern margin of the eastern lobe of the complex. The presence of these magnetic anomalies is consistent with the magnetite rich nature of the marginal zone of the complex (see Chapter 3). A comparison of Figure 19 with the general geology of the area (Figure 2) shows that several other rock units contain distinctive magnetic anomalies. The sediments in the southern part of the area are particularly conspicuous due to their iron formations. The volcanic rocks generally contain weaker and more erratic

gnetic anomalies, but these contrast well with the magnetite poor granitic intrusions as in the area north of Ramsay Bay. Three northeast trending diabase dykes, which cut across all other rocks in the area, are defined by linear magnetic anomalies in the northwestern and southeastern parts of the area.

Grid Area Magnetometry Within the grid area a ground magnetometer survey was conducted to help extend lithologies into covered areas. Figures 20 and 21 show the contoured data. Appendix IV describes the survey procedure. A comparison of Figure 20 and 21 with the geology in Figures 11 and 12 shows that unit 2 and often unit 1 are characterized by strong magnetic anomalies. As mentioned in Chapter 3 both of these units contain distinctive magnetite and pyrrhotite mineralization. The strongest magnetic anomaly within the grid area is centered over unit 2 across the northwestern part of the grid (Figure 21). In Figure 19 this anomalous area does not extend far outside of the grid area. Therefore, unit 2 appears to be only locally present within the complex. Unit 1 is well defined by lower order magnetic 46

malies which contrast with adjacent units in the orthern and central parts of the grid. The southeastern corner of the grid is the only ether major area with significant magnetic anomalies. Magnetite was noted in this area mainly in the 2 - 4"

mafic rich layers in gabbro. No distinct change in rock type was observed in the rare outcrops in this area, so a discrete mappable unit was not defined. Since the northwestern boundary of this anomalous area parallels the northeast trending stream valleys and not the unit 1 pyroxenite, a faulted boundary is suspected. This anomalous area is seen in Figure :L9 to correspond with the anomaly along the southern margin of the eastern lobe of the complex. As mentioned earlier, this anomaly appears to be the eastern continuation of the southern marginal zone in the western lobe of the complex. 49

TER V PETROGRAPHY

Gabbros Gabbro is the most common rock type within the eastern lobe of the Bell River Complex. Within the grid area units 3, 4 and the major part of unit 2 consist of gabbros. Aside from the variations in mafic and felsic minerals, these gabbros are very similar petrographically and will be discussed together. Forty-three rock samples were collected at roughly 200 ft. intervals along lines 28N and 204N to investigate the gabbros in more detail. In addition 19 grab samples were collected within the area (Appendix I). In thin section, the gabbros consist of varying proportions of hornblende or actinolite and plagioclase with minor chlorite, biotite, sulfides, magnetite and ilmenite.

Amphibole The typical gabbro contains a moderate to strongly pleochroic amphibole (hornblende/actinolite) with a = pale greenish yellow, S = deep green, and ô = bluish green. Five morphologic varieties of amphibole have been recognized in thin section which appear to represent 50

a progressive alteration of an original pyroxene. About one half of the gabbro samples contain an amphibole assemblage which appears to be one step removed from an original pyroxene. This assemblage typically consists of weakly to moderately pleochroic hornblende or actinolite that contains small (< .01 mm) irregular shaped quartz blebs. The identity of the quartz was verified in the microprobe. Similar amphibole + quartz textures have been noted in dolerites by Sutton and Watson (1951) and Spry (1969). The relationship of this assemblage to an original pyroxene was only observed in two sections (T-40 and T-33) where the replacement of clinopyroxene is not complete (Figure 22).

Figure 22 Clinopyroxene (botto centre) partially replaced by hornblende + quartz (T-40). 51

The amphibole + quartz assemblage occupies intercumulus areas between plagioclase grains in most of the bleby anorthosite and a few anorthositic gabbro samples. These areas are typically about 2.5 mm in diameter, but they range up to 15 mm. The amphibole in these areas optically behaves as one grain indicating the replacement of an original pyroxene oikocryst (Figure 23). These observations confirm field suspictions on the identity of the "blebs" in the bleby anorthosite.

Figure 23 Cumulus plagioclase within a large poikiblast of hornblende + auartz,slightly disrupted by further hornblende growth (T-13). 52

In the majority of the gabbro samples, the amphibole + quartz assemblage doesn't have a clear intercumulus position. In these samples .5 - 5 mm areas (2 mm average) act like one amphibole grain. Larger areas are made up of several smaller amphibole + quartz areas with different extinction positions. In these samples the amphibole + quartz probably represents an original cumulus clinopyroxene. The amphibole + quartz assemblage is very often disrupted by further amphibole growth. The first stage of this growth appears to be the replacement of the amphibole + quartz by an oriented matt of 0.1 - 0.5 mm amphibole. Figure 24 shows a hornblende + quartz area partially replaced by oriented hornblende and Figure 25 is a completely replaced area. No quartz remains in most of the areas with this amphibole morphology but when present it is much coarser (.1 mm) than in the original amphibole + quartz assemblage. A possible variant of the oriented amphibole morphology is present in five gabbro sections. This morphology consists of parallel fibers of hornblende or actinolite, with nearly the same optical orientation, in bundles up to 10 mm in diameter. Euhedral hornblende crystals (.1 - .3 mm in size) are often present 53

within the bundles (Figure 26).

Figure 26 Large area of fibrous hornblende containing euhedral hornblende (T-301

More intensive amphibole recrystallization results in a replacement of the oriented amphibole crystals by a matt of randomly oriented amphibole. This amphibole is anhedral to subhedral, moderately to strongly pleochroic and typically .2 - .5 mm in diameter. Figure 27 shows an area of oriented amphibole partially replaced by randomly oriented grains. Figure 28 shows a typical area that has been completely replaced. When this recrystallization is intense the amphibole growth into Figure 27 Area of oriented hornblende crystals partially replaced by randomly oriented hornblende (T-40)

Figure 28 Plagioclase with finer grained, randomly oriented hornblende (T-31) 56

acent plagioclase completely destroys the original afic magmatic texture (Figure 29). This random amphibole morphology is the most common type observed in thin section. It is very often present with the amphibole + quartz assemblage and may represent an alternative alteration made to the oriented amphibole morphology. • A variation of the random amphibole morphology was seen in two sections from the eastern end of line 28N. In these samples a coarser grained (.5 - 1 mm) hornblende is present (Figure 30). It is subhedral to euhedral, deeply pleochroic and lacks the "ragged" appearance of the more typical random amphibole morphology. Similar, but smaller (.1 - .3 mm) euhedral metamorphic amphibole is present in other gabbro samples along with metamorphic plagioclase (see next section). This similarity combined with the proximity of this part of the grid to the granitic intrusion to the east (Figure 9) indicates that this amphibole is metamorphic and not a cumulus phase.

Plagioclase Plagioclase feldspar is the other major constituent of the gabbros. Two types of plagioclase are present 57

Figure 29 Plagioclase partially replaced by randomly oriented amphibole

Figure 30 Large subhedral to euhedral hornblende with ^lagioclase (T-1) 58

Lain section: a primary igneous plagioclase and a ndary metamorphic plagioclase.

igneous Plagioclase The igneous plagioclase ranges in composition from bytownite to labradorite (Chapter VI). It exhibits albite or more rarely pericline and carlsbad twinning. Rare grains are weakly zoned, but this zoning could not be detected on the microprobe. Plagioclase ranges from fresh to highly sericitized, sauceritized, or replaced by metamorphic plagioclase. Usually, however, it is only slightly sericitized and contains about 3% metamorphic plagioclase. Igneous plagioclase occurs as anhedral grains from 1 - 5 mm in size (maximum 15 mm). It is therefore usually coarser grained than the associated amphibole. In the felsic rich gabbros it has a nice adcumulus texture (Figure 31). A mesocumulate texture is also noted in parts of these samples (Figure 23). The original plagioclase textures in the mafic rich samples has usually been destroyed by amphibole recrystallization. The plagioclase grains in about 40% of the gabbro samples show evidence of tectonic activity. They are often bent or broken and have offset twin lamellae (Figure 32). Secondary plagioclase and hornblende are 59

Fi7ure 31 Fresh adcumulus plagioclase (T-36)

Figure 32 Broken plagioclase crystal with metamorphic plagioclase and hornblende in the cracks (T-6) 60

usually present in the fractures. This fracturing has no doubt aided fluid movement and faciliated the metamorphism of the complex.

Metamorphic Plagioclase Metamorphic plagioclase is present in about 60% of the gabbro samples where it typically makes up 1 - 5% (maximum 20%) of the rock. It ranges in composition from anorthite to andesine and occurs as anhedral grains that are usually .05 - .2 mm in diameter (range from .01 - .5 mm).. These grains are often strongly zoned (see Chapter VI), but only rarely twinned (Figure 33). This plagioclase is always fresh, even when the primary plagioclase is altered (Figure 33). Metamorphic plagioclase occurs along grain boundaries and within cracks of the primary' plagioclase (Figure 34). It is usually associated with small metamorphic hornblende or actinolite.

Minor Minerals Chlprite is occasionally seen in the gabbro samples. When present it usually makes up 1 - 5% of the rock and is associated with the other mafic minerals. Biotite is rarely present in the gabbros and ranges from a trace to 2% of the rock. It is very Figure 33 Fresh metamorphic plagioclase and hornblende with moderately sericitized igneous plagioclase (T-15) .

ragged and appears to be metamorphic. Magnetite and ilmenite are occasionally seen in the more mafic gabbros as isolated intercumulus grains. When present they make up 1 - 5% of the sample. Erratic sulfide mineralization is present in the gabbros. Pyrrhotite (monoclinic) and chalocpyrite with minor pyrite are the most common phases. Pentlandite and millerite were observed in two samples. The best mineralization (2 - 3% sulfides) was seen in felsic rich gabbros which are very badly sericitized and/or sauceritized. Figure 35 shows an example of the best mineralization. Thompsonite and epidote veinlets about .1 mm wide were only rarely noted in a few gabbro samples.

unit 1 A total of 28 pyroxenite samples from unit 1 were

Examined in thin section (Appendix I). The majority of the samples come from a detailed sampling of this unit at 50 ft. intervals on lines 156N and 160N. Random grab samples were collected from the other unit 1 occurrences. One sample also comes from the 2 - 4" wide pyroxenite layers in gabbro on line 24N - 31 + 46E. In general all of these samples were found to be very similar. The typical pyroxenite consists of adcumulus clinopyroxene with a 1 - 3 mm grain size (up to 11 mm in the coarser samples). The clinopyroxene was optically identified as augite with a 2V of 40° - 45° and a (+) sign. The pyroxenites are variably uralitized to a fine grained (.05 - .2 mm) assemblage of hornblende or actinolite (Figure 36). This alteration begins at grain margins and follows cleavages often leaving small rectangular islands of fresh pyroxene. In moderately uralitized samples the amphibole crystals often show an orientation related to the original pyroxene. In highly altered samples, however, there is no indication of an original pyroxene and the b4

Figure 36 Partially uralitized augite with intercumulus opaques (magnetite) (T-60).

uralite crystals are randomly oriented. Both of these textures are similar to amphibole morphologies in the gabbros. The unit 1 pyroxenites, unlike the other rock types in the eastern lobe of the Bell River Complex, usually contain sulfide mineralization. An average of 1% disseminated sulfides is usually present, but locally up to 10% sulfides are observed. These sulfides mainly show a magmatic/intercumulus relationship to the pyroxene. However, small (< .1 mm) chalcopyrite 65

veinlets cutting pyroxene and small rods (.02 mm wide) of pyrrhotite within uralitized pyroxene are rarely observed. Monoclinic pyrrhotite is the major sulfide in the pyroxenites. It is occasionally altered to marcasite and often contains exsolution flames of pentlandite. Typical pyrrhotite grains are .05 - .2 mm in diameter with rare intercumulus areas up to 2 mm. Chalcopyrite is often present (Tr - 1%) and is usually associated with the pyrrhotite (Figure 37). Discrete grains of pent-

dite,associated with pyrrhotite, were only observed two sections. The unit 1 pyroxenites typically contain 1 - 2% ntercumulus magnetite, but amounts up to about 10% are not uncommon. A trace amount of ilmenite is occasionally associated with the magnetite. The ilmenite usually occurs as discrete grains, but two sections contain both ilmenite grains and exsolution lamellae in the magnetite. The grain size of the magnetite is usually .1 - .5 mm; some intercumulus grains are up to 2 mm. One sample from unit 1 is unique and deserves individual mention. Sample T58 was collected from unit 1 on line 128N. It contains large (up to 6 mm) orkocrysts of an orthopyroxene that was optically identified as hypersthene (2V ti 60° and a (-) sign). This orthopyroxene typically shows irregular exsolution blebs of clinopyroxene (Figure 38). In some grains two groups of exsolution lamellae are evident. A narrow group (< .01 mm wide) is parallel to 100 and a broader set (.01 - .02 mm wide) is nearly parallel to 101 of the host hypersthene. According to Poldervaart and Hess (1951) this type of exsolution is typical of Figure 38 Adcumulus augite with poikilitic inverted pigeonite (T-58)

Figure 39 Closeup of figure 38. Augite with two sets of exsolution lamellae and one large oikocryst of inverted pigeonite. 68

inverted pigeonites. This pigeonite appears to have originally occurred as large oikocyrsts in this sample since groups of individual orthopyroxene grains now have exsolution blebs with similar orientations (Figure 39). The cumulus clinopyroxene in sample T58 is also unique because it contains visible orthopyroxene exsolution lamellae. Most grains have a fine set (< .01 mm) parallel to 100, but a few grains also have a coarser (.02 mm) set parallel to 001 (Figure 39). These exsolutions indicate that the original composition was more iron rich than Wo41En44Fs15 (Poldervaart and Hess, 1951). Sample T58 shows an extremely variable degree of uralitization. Parts of the slide are fresh and others completely uralitized. In the intermediate areas the clinopyroxene remains unchanged, but the orthopyroxene exsolutions have been completely uralitized. The resulting texture is very similar to the majority of the unit 1 samples and indicates that they could have had similar exsolutions. Two other grab samples (4321 and 4322) were collected from the same area as T58. They do not show 69

y evidence of pigeonite or exsolution lamellae in e clinopyroxene. These two samples, however, are badly uralitized.

Unit 2a A total of 15 samples from units 2a were examined by polished thin section (Appendix I). All samples come from the body north of the grid (Figure 12). Eleven of the samples were collected at 25 ft. intervals across this unit and the remaining four samples were collected at 50 ft. intervals along the eastern margin of the unit. Dunite, in varying stages of alteration, is the most common rock type in this unit. A few samples are very fresh and appear to be representative of the entire unit. These samples consist mainly of cumulus olivine with intercumulus magnetite (8 - 35%) and ilmenite (1 - 5%). Therefore, unit 2a is more correctly called a magnetite-ilmenite dunite. The olivine in these samples occurs as 1 - 5 mm rounded to subhedral grains that are often completely surrounded by magnetite + ilmenite (Figure 40). Heinrich (1956) calls this a sideronitic texture. 'Figure 40 Cumulus olivine with intercumulus magnetite + ilmenite. Note ser-- ventine and chlorite alteration at olivine grain margins (25-4).

Figure 41 Ilnenite grains (light tan) and exsolutions in magnetite (25-10) (reflected light). 71

The magnetite and ilmenite are always intimately associated. The ilmenite mainly occurs as anhedral ;rains .1 - .5 mm in diameter at magnetite grain boundaries. It also occurs as exsolution lamellae .05 - ,5 mm wide along the (111) direction of magnetite. In both cases the ilmenite appears to have exsolved from the magnetite. Ilmenite grains and exsolutions often occur together in the same sample (Figure 41). Only five of the samples taken across unit 2a are relatively fresh and these occur near the center of the unit (Figure 42). The olivine alteration in this area is mainly serpentinization. The serpentine cuts the olivine along random fractures and occurs around grain boundaries. Some chlorite is often present and is concentrated around the olivine grain margins. A minor amount of iddingsite is also present. The samples near the margins of the unit are more intensely altered and only one sample (25-1) contains a trace of olivine. In these altered samples the olivine crystals are now a fine grained (.1 - .5 mm) matt of talc + tremolite + chlorite. Similar talc rich margins are reported on Alpine peridotites (Jahns, 1967). The symetry of the alteration in the unit indicates

2Mg3Si205(OH)4 + 3CO2 --4 Mg3Si4010(OH)2 + 3MgCO3 + 3H20 serpentine talc

Although carbonates were not recognized in the observed sections, a carbonate rich zone could have been missed by the employed sample spacing. Several of the samples collected from unit 2a contain some clinopyroxene. Cumulus clinopyroxene is present in four samples. Sample 25-6 contains about 35% cumulus clinopyroxene in addition to olivine and oxides and is therefore a magnetite-ilmenite peridotite. Cumulus pyroxene is seen in 1/2" wide clinopyroxenite layers in samples 25-5 and 25-9. Sample 25-8 only contains uralitized pyroxene with intercumulus magnetite + ilmenite and is a true pyroxenite. Partially uralitized clinopyroxene occurs as up to 4 mm intercumulus areas in sample 25-4. Because the pyroxene is intercumulus, this sample is still correctly 74

called a dunite. As seen in Figure 43, the pyroxene in this sample has an intercumulus relationship with both olivine and magnetite. This relationship suggests that the intercumulus oxides in unit 2a could represent a cumulate phase which underwent 4adcumulate growth.

Figure 43 Intercumulus uralitized clinopyroxene with cumulus olivine and magnetite + ilmenite (25-4).

Lamprophyre Dykes Nine samples of lamprophyre dyke material were examined in thin section (Appendix I). These samples 75

have a xenomorphic granular texture. The grain size is typically 0.1 - 0.3 mm; coarser varieties are up to 0.7 mm. Figure 44 shows a typical section.

Figure 44 Lamprophyre dyke (T-16)

Because of the fine grain size each sample was point counted. Table 3 summarizes the mineralogy. 76

Table 3 mean % range % hornblende 44 16-77 plagioclase 32 17-47 quartz 16 0-54 biotite 4 0-13 opaques 1.5 0-5

The hornblende in these samples appears to be primary. It is strongly pleochroic in shades of green and occasionally ô = bluish green. The plagioclase is often fresh or slightly sericitized, but several samples are badly sericitized. In two of the quartz poor samples, the plagioclase was found to be labradorite (see Chapter II). Sample T16 contains about 10% quartz and the plagioclase is more acidic (andesine). The opaque minerals are mainly ilmenite, but minor amounts of pyrite, pyrrhotite and chalcopyrite are present. Almandine garnet poikiblasts 5 mm in diameter were only observed in two samples (T82, 4289) from unit 5 (Figure 11). The biotite appears to be primary. The biotite and hornblende in about half of the sections have a pronounced orientation. In the field this was recognized as a schistocity parallel to the 77

trusive contacts. Sample (T54) was taken of one of these contact zones. In thin section the plagioclase in the gabbro shows evidence of cataclastic activity and the hornblende shows an orientation parallel to the dyke contact. The mafic minerals in the dyke are also parallel to the contact. These observations are consistent with the field relations (Chapter 3) which indicate intrusion of some lamprophyre dykes into fault zones. Claveau (1951) classifies the lamprophyre dykes as hornblende kersantites (Johannsen, 1937). The results of this study confirm this classification.

Granitic Intrusions

Ten representative samples of the granitic intrusions were examined in thin section (Appendix I). Four samples were collected from the large intrusion east of the eastern lobe of the complex. Three of these samples are fine to medium grained granites with 14 - 34% plagioclase, 30 - 44% quartz, and 20 - 41% microcline. One sample is a fine to medium grained hornblende syenite with 68-78% microcline, 10 - 20% plagioclase and about 7% hornblende. 78

No samples were collected of the main Olga quartz diorite, but most of the granitic dykes within the com- plwx are similar to reported compositions. These dykes rw fine to medium grained biotite or biotite-hornblende quartz diorite. They contain 30 - 53% plagioclase, 36 - 59% quartz, 5 - 9% biotite and 1 - 6% hornblende. One dyke sample is similar to the granites described above.

Diabase Two samples (T61, T62) of fine grained diabase were collected in the eastern lobe of the complex. Sample T62 was collected on line 188N where patches of diabase remain on a vertical north facing cliff of complex gabbro. Sample T61 comes from a small exposure about 1.2 miles west of BLO 116N. Both samples are very similar. They have a remnant diabasic texture with 2 - 9 mm laths of completely sericitized plagioclase p.henocrysts in a .05 - .15 mm mass of hornblende or actinolite and serpentine. A point count of T61 gave the following results: plagioclase 56.0% hornblende + actinolite 25.8% serpentine 8.7% 79

opaques (magnetic) 6.6% biotite 3.0%

One medium to coarse grained gabbro sample (T59) from BLO-187N, is also thought to be diabase. This sample has a nice ophitic texture with laths of badly sericitized plagioclase enclosed by fresh clinopyroxene oikocrysts (Figure 45). Euhedral apatite and anhedral olvine and biotite are also present. The olivine has an optically determined composition of Fo67.

visual estimate of the mineral percentages in the is as follows: plagioclase 78% augite 10% opaque (magnetic) 5% olivine 3% apatite 3% biotite 1% The alteration style, texture,and apatite content of sample T59 are unlike any other complex gabbro sample. Similar descriptions of diabase dyke material by Auger (1942) and Freeman and Black (1944) indicate that this sample is diabase. Samples T61, T62 and T59 appear to come from one diabase dyke which cuts through the eastern lobe of the complex with a N70°E strike. This dyke shows up nicely on the regional aeromagnetic map (Figure 19) as a linear anomaly which includes the diabase outcrops described by Freeman and Black (1944).

Western Lobe - Petrography Fifteen samples were collected from the western lobe of the Bell River Complex to make a comparison with the eastern lobe. In addition, three Wabassee volcanics 81

les were collected north of the complex (Appendix I). The main difference noted between the western and astern lobe gabbros is in the style of alteration. unlike the eastern lobe samples there is no metamorphic plagioclase, only one amphibole morphology (an oriented grain replacement of pyroxene during uralitization), a pervasive chloritization, a general sauceritization of the plagioclase, and an alteration of the oxide phases to sphene. Several samples from the western lobe were also different mineralogically or texturally from those in the east. Sample 16-1 was collected at Chenal Rapids approximately 4,700 ft. from the northern contact (Figure 65, Appendix I). It is a norite with about 71% cumulus hypersthene, 20% cumulus plagioclase, 5% intercumulus plagioclase, 3% intercumulus augite, and 1% chlorite. Figures 46 and 47 show the textural relationships. The hypersthene (2V ti 45°, (-) sign) is largely uralitized, but a few cores still remain. No samples from the eastern lobe were seen with intercumulus plagioclase or cumulus orthopyroxene.

Two gabbro samples from the western lobe contain 82

quartz. Sample 13-1 is an anorthosite from Chenal lta$ids. It has a mesocumulate texture with about 7% intercumulus quartz and a trace of apatite. Sample 19-2 is a gabbro collected about 3,000 ft. downstream from mignon Rapids where a quartz gabbro is exposed for 2,000 ft. along the southern shore of the river. The thin section was cut from an anorthositic part of the sample with a xenomorphic texture and about 20% quartz. Both of these samples come from the marginal zone of the complex which was the top of the Bell River Complex before folding. Therefore is is not surprising to see some rocks from this zone with quartz and apatite. Two samples were collected from a pyroxenite at Cold Spring Rapids. Unlike the unit 1 pyroxenites in the eastern lobe,these samples appear to have originally had both cumulus and intercumulus orthopyroxene (now uralitized or altered to talc + chlorite). Sample 16-3 was collected near the center of the 1200 ft. thick subsidiary gabbro intrusion just north of the Bell Channel deposit (Figure 65, Appendix I). It is a fine to medium grained pyroxenitic gabbro with a xenomorphic texture. A point count gave the following mineralogy: 84

hornblende 47.4% plagioclase 40.6% opaques 4.9% epidote 3.8% chlorite 2.7% quartz 1.0% Aside from its finer grain size it is similar to samples from the margin zone of the complex. The three volcanic samples were not investigated in detail because of their very fine grain size and alteration. 85

MINERAL CHEMISTRY AND METAMORPHISM

The first section of this chapter includes a discussion of the mineral chemistry of primary plagioclase, metamorphic plagioclase, clinopyroxene, olivine, amphibole, sulfides and oxides. The second part incorporates the mineral chemistry and petrography in a discussion of Lhe metamorphism in the eastern lobe of the Bell River Complex.

Mineral Chemistry Chemical compositions of plagioclase, pyroxene, olivine, amphibole, sulfides and oxides were obtained using the energy dispersive system on the elctron microprobe within the Geology Department. The details of the procedure and the individual results for each mineral are included in Appendix II. The majority of the probe work was carried out to investigate any cryptic variations within the cumulus minerals in order to assist in top determinations within the eastern lobe of the complex. As mentioned in Chapter II, the overall structure in this area is not as well understood as in the western lobe. 86

''''â ioclase Plagioclase feldspar is the only cumulus phase { resent throughout the investigated part of the Bell River complex. It is therefore the most useful mineral to define any cryptic variations within the complex. Of twenty seven rock samples collected along 1ixe 204N, twenty contained plagioclase feldspar that was considered fresh enough to analyse using the microprobe. In addition, the plagioclase in five samples collected near line 204N was also analysed. The primary plagioclase in these samples is often slightly to moderately sericitized. The slides usually contain about 3% metamorphic plagioclase (up to 20%) and more rarely about 3% epidote (up to 20%). More details on the mineralogy of these samples is included in Appendix I. In general about 20 spots were analysed on seven different primary plagioclase grains in each sample. The atomic proportions for each sample are summarized in Table 4. The plagioclase compositions across line 204N are plotted in Figure 48. As seen in Figure 48 the primary plagioclase is mainly bytownite with several samples falling in the lower labradorite field. Although these samples con- Table 4. Primary Plagioclase Feldspar Compositions (atomic proportions based on 8 oxygen).

in quite variable amounts of epidote and metamorphic

plagioclase (see Figure 48) these constituents don't appear to have significantly affected the primary plagioclase compositions. Within unit 4 (felsic gabbro) at the western end of line 204N, the plagioclase is about Ably. The Na content quickly increases and peaks at about Ab37 within unit 2. This is the mafic rich unit that contains significant magnetite and ilmenite mineralization (Chapter III). Only one sample was analysed from unit 4 east of unit 2, but the Na content is still relatively high (Ab29). The Na content then drops to about Ab25 and remains fairly constant throughout unit 3 (gabbro). These results indicate that the stratigraphic tops in this area are to the east, since the more Ca rich plagioclase is present at the western end of line 204N. The cause of the rapid increase in the Na content of the plagioclase within unit 2 is not entirely clear. A comparison with other large igneous complexes, such as the Bushveld and Skaergaard, shows that magnetite precipitation occurs near the tops of these intrusions when the plagioclase compositions are in the andesine range. The magnetite is accompanied by cumulate apatite and iron rich olivine. The Bell River magma was precip- 90

}tiny bytownite, and unlike those intrusions the plagio- ~E, ise shows a major increase in the sodium content within the magnetite unit. A possible explanation for the observed cryptic var-

iation is the fractional crystalization of a rap- idly decreasing volume of magma followed by a new influx of magma near the unit 4/ unit 3 boundary. A problem with this idea is that the observed clinopyroxene compositions are more consistent with normal differentiation (see page 99 ). Considering the limited pyroxene data and the anomalous nature of the pyroxene in unit 2a (see page 104), the plagioclase data are probably more reliable.

In addition to the plagioclase analyses along L160N, several other samples are included in Table 4. Samples T7 and T8 come from the southern part of the grid near the eastern end of line 28N. They have similar compositions (about Ab30) which is only slightly more sodic than the samples from the eastern end of line 204N (Figure 48). These results are consistent with a higher stratigraphic position and indicate that no major movement has occurred along the inferred northeast trending faults in the grid area (Figures 11 and 12).

Samples 16-1, 15-1 and 13-2 come from the western 41

of the complex. They were collected in the vicinity

of Chenal Rapids and come from a zone approximately 44,000 ft. from the northern contact of the complex (Figure 65, Appendix I). Sample 15-1 comes from a vagnetite rich zone 150-200 ft. thick in the area. If Sharpe's (1968) geology is correct, sample 16-1 is about 1,000 ft. stratigraphically below the magnetite rich unit and sample 13-2 about 300 ft. above it.

The more sodic rich nature of 13-2 (Ab33.0) compared to 16-1 (Ab28.0) is consistent with their stratigraphic positions. The significantly more sodic nature of the plagioclase in 15-1 (Ab41`5) is similar to the results found within unit 2 in the eastern lobe.

Sample 16-1 also contains intercumulus plagioclase (Figure 47). Three spots on one grain were analysed and a composition of Ab30.2 was obtained. This is slightly more sodic than the cumulus plagioclase and is consistent with a later crystallization as an intercumulus phase. The plagioclase in three samples of lamprophyre dyke material was also analysed on the microprobe (Table 4). The results are highly variable and range from labradorite in samples T79 and T54 to andesine in T16. 92

tamc,r hic Plagioclase As stated in Chapter V, metamorphic plagioclase a common constituent of the gabbros in the eastern

obe of the Bell River Complex. A representative number of samples were analysed on the microprobe and the results are summarized in Table 5. A large range in

composition from Ab7.6 to Ab50.9 (anorthoite to andesine) is present in these samples. Metamorphic plagioclase is often moderately to strongly optically zoned. In order to investigate this zoning in more detail, microprobe traverses were carried out across several of the larger zoned crystals in two samples (Figure 49). These grains show variable results. Nearly half of the crystals show no chemical zoning. The other half have a weak to strong reversed zonation. The largest observed change is from an Ab57.1 core to Ab46.1 rim. One grain is normally zoned with an Ab55.1 core and Ab59 8 rim.

Pyroxene Unit 1 is the only unit in the grid area that contains significant quantitites of cumulus pyroxene. In order to investigate any cryptic variations, eight samples were collected across this unit 93

WAS analysed on the microprobe. In general about 20 spots were analysed on 5 to 7 grains in each sample. The results are summarized in Table 6. Figure 50 is a plot of the relative percentages

of the molecular proportions of Fe, Mg and Ca in the pyroxenes on line 160N. The results are very similar and show no variation across the unit. Only grab samples were collected from the other unit 1 occurrences, but if the results for line 160N are typical, these samples should be representative of each location. In addition, two samples were collected from unit 2a that contain some fresh pyroxene. Table 6 summarizes the microprobe results for the pyroxenes in these grab samples.

) just to the north of the grid (Figure 12). The

nncpyroxene in sample 25-4 is intercumulus and lar in composition to the cumulus pyroxene in 25-6. :fore sample 25-4 is a heteradcumulate (Wager and 1967). Sample 27-5 is from the previously

mentioned unit 1 on line 160N. Samples 4322 and 4321 come from unit 1 near the eastern end of lines 116N and 124N respectively (Figure 12) and as expected are similar in composition. These five samples show a definite pattern of iron enrichment from west to east across the grid. This observation supports the idea that the stratigraphic tops of these rocks is to the east. Three other clinopyroxene samples are also plotted in Figure 51. Samples 4286 and 4288 come from unit 1 on lines 140N and 156N respectively (Figure 11). They are very similar in composition to 4321 and 4322 indicating that the southern pyroxenite continues north into the east-central part of the grid. The T58 clinopyroxene analysis shown in Figure 51 is from the unusually fresh sample described in Chapter V. In the marginally uralitized parts of this sample the orthopyroxene exsolution lamellae have 100

en preferentially altered with a resulting texture Very similar to most unit 1 pyroxenites. The

similar composition of the pyroxene in sample T58 with the two other samples from the same unit (4321

and 4322) tends to support the idea that these samples originally had similar exsolutions, particularly if the lower Ca content of sample T58 is due to inclusion of some very fine orthopyroxene

lamellae (Ca.03Mg,98Fe.95Mn.01Si1.98A1.0406). The intercumulus inverted pigeonite in sample T58 was also analysed and the results are included in Table 6. The host orthopyroxene has a composition of Ca_ 03 and the Mg1.02FE.93Mn 01Si1.97A1.04C6 exsolved clinopyroxene Ca.90 Mg_68Fe.36Si1.97A1.06 Ti ,01C6. In general the samples in Figure 51 show a differentiation trend similar to alkali basalt magmas such as the Black Jack teschenite sill (Wilkinson, 1957). However, clinopyroxene is the only pyroxene phase to crystalize from these alkali magmas (Deer et al., 1963). Both cumulus and intercumulus orthopyroxene are present in several samples from the western lobe of the Bell River Complex and intercumulus pigeonite is present in sample T58 from the east. Therefore, it seems unlikely that the complex is an alkali magma. The cause of the Ca rich nature lol

the pyroxenes, however, is not clear.

Olivine Cumulus olivine was only observed within the

eastern lobe of the Bell River complex within unit

2a (Figure 12). Eleven samples were collected across this unit north of line 208N, but only six

contain fresh olivine which was analysed on the micro-

probe. About twenty spots per sample were analysed

on five to seven grains per sample. The atomic

proportions for the samples are shown in Table 7 and

the forsterite contents are plotted in Figure 52.

Excluding sample 25-1, the results indicate

that there is little variation across this unit.

Sample 25-1 is considered less reliable, because only

a few very ragged olivine grains are present in the

section. It is thought that the results represent

some talc contamination. Two analyses are shown for

sample 25-3. The majority of the grains average about

Fo6 , but one grain is much higher at Fo64. This

grain shows no indication of alteration, so the

difference appears to represent an original variation. Samples 25-4 and 25-6 also contain clinopyroxene which was analysed on the microprobe (see previous section) The work of Medaris (1969) indicates that an orthopyroxene 102

n coexisting calcium rich and calciumpoor pyroxenes is lightly lower in the calcium rich pyroxene. Therefore,

tp1e clinopyroxenes in these two samples appears to be 'anomalously magnesium rich for the observed olivine composition. The cause of this magnesium rich nature is not clear, but it could indicate a nonequilibrium condition. The composition for the olivine in unit Fo63-64 2a is very similar to values reported by Allard (1976)

for a similar unit in the Dore Lake complex. The iron rich nature of this olivine is also similar to olivine near the top of large layered intrusions (Wager, 1968). The average MnO contents of the olivine in unit 2a ranges from .27 to .45%. These values are similar to other olivines with this composition (Simkin and Smith, 1970). The NiO content is below the detection limit (.1 wt %) for the method used. Low NiO values are expected in olivines of this composition (Simkin and Smith, 1970). 105

Na systematic attempt was made to analyse the boles in the Bell River complex rocks. A few

m,'es were analysed to verify the optical determin-

t'ons and several amphiboles were analysed while

ÿernpting to do the pyroxenes.

The microprobe results are summarized in Table

8 and plotted in Figure 53. Most of the samples, as expected, fall in the tremolite-actinolite or hornblende series. One lamprophyre dyke sample

(4289-B) is a cummingtonite.

Sulfides and Oxides The sulfide and oxide phases in the Bell River Complex samples were not analysed in detail on the microprobe. Selected samples were analysed to verify the optical determinations. The sulfide analyses are summarized in Table 9. In general the results are nearly stoichiometric except for the cobalt contents. The Co contents of pyrite and pentlandite are similar to other pentlandite-pyrite-pyrrhotite Table 9. Sulfide Compositions.

emblages (Harris et al., 1972). The cobalt values the pyrrhotite and chalcopyrite, however, are higher

n the maximum values of .85% and .2% respectively reported by Levinson (1980). The cause of these high values is not known.

The Ni contents of pyrrhotite and pentlandite

are average (Levinson, 1980; Harris et al., 1972). The mean atomic percent metals in the three pyrrhotite samples is 46.8 (4340), 46.8 (4343) and 46.5 (T-16). These values fall in the monoclinic field as expected (Yund and Hall, 1969). The magnetite and ilmenite analyses are summarized in Table 10. They are not anomalous.

Western Lobe Metamorphism Previous workers in the Matagami area have noted a regional greenschist metamorphism (Freeman,1939; Sharpe, 1968; Beland 11953). This metamorphism is characterized by alteration of the mafic minerals of the volcanics to uralite, chlorite, epidote and magnetite. The plagioclase feldspars are often clouded with secondary minerals or replaced by saussurite. Within the Bell River Complex, Freeman (1939) notes that pyroxene is replaced by either 110

rpentine + subordinate hornblende + calcite or gregate of hornblende + chlorite + calcite + quartz. ag The plagioclase is altered to varying degrees to a matt of epidote + calcite + quartz + acid plagioclase. In other areas it is fresh except for replacement by chlorite along cracks. Leucoxene often replaces titan- iferous magnetite. The 15 samples from the western lobe of the complex that were examined for this project verify Freeman's observations of low grade alteration. The presence of contact metamorphism around granitic intrusions north of Matagami has been noted by Sharpe (1968). This metamorphism is generally characterized by blackened and coarsened volcanics and on the Garon Lake Mines property by a cordierite- anthophyllite hornfels.

Eastern Lobe Metamorphism

The rocks within the eastern lobe of the Bell River Complex have been subjected to a different metamorphic history from those in the west. This metamorphism has resulted in a typical gabbro mineral assemblage characterized by moderate to strongly 111

eochroic (blueish) amphibole and a fresh to slightly ericitized or sauceritized primary bytownite- ebradorite. Minor phases include metamorphic plagio- Ik lase+chlorite+biotite+almandine (rare). The meta- orphie plagioclase in this paragenesis is the most ► diagnostic of the metamorphic conditions. The intensity of the alteration within the eastern lobe is highly variable. The observed sections often contain fresh igneous mineralogy, but even within the scale of a thin section the alteration can become very intense. This variability is probably due to the non uniform access of water throughout these rocks. This access was mainly controlled by tectonic brecciation exemplified by the deformation textures in primary plagioclase (see Chapter V). The metamorphic plagioclase in the eastern lobe of the complex ranges in composition from An49.1 to An 92.4 (see previous section). This calcium rich nature is indicative of high temperature metamorphic conditions (Lyons, 1955; Miyashiro, 1973; Winkler, 1976). Unfortunately, a reliable scale relating the plagioclase composition to temperature does not presently exist. Nevertheless, if the boundary between 212

wepidote-amphibolite and amphibolite faices is (Miyashiro, 1973), the calcium rich en'at An30 atüre of this plagioclase points to amphibolite grade iitamorphism. Miyashiro, 1973, notes the presence of amphiboles

lm metabasites. Actinolite is usually present from

upper prehnite-pumpellyite to lower amphibolite facies and hornblende is present from upper greenschist to upper

-amphibolite facies. The presence of both actinolite and

hornblende in the complex gabbros is therefore consistent

with amphibolite grade metamorphism. Chlorite is present in metabasites under low

pressure environments from greenschist into the

lower amphibolite fades (Miyashiro, 1973). Its

general absence from the complex rocks supports

higher grade metamorphic conditions.

The stability range for biotite in metabasites

is from lower greenschist to lower granulite facies

(Miyashiro, 1973). Therefore, its rare presence does

not help define the metamorphic conditions.

The erratic formation of almandine in the 113

ros and lamprophyre dykes,despite favorable whole chemistry, is consistent with lower pressure ibolite metamorphism. Miyashiro (1973) ieves that reducing conditions may be one of the factors controlling almandine formation. He notes that the oxidation state in metabasites is

highlyhl variable so formation will be erratic. Epidote under low pressure regional metamorphic conditions is present from greenschist to lower amphibolite conditions. Figure 54 is a plot com- paring the relative amounts of epidote and metamorphic plagioclase within the gabbro samples.

ere is a negati ve correlation which is consistent ith the high temperature metamorphic conditions for the secondary plagioclase. postulated The rarity of sphene as an alteration product of ilmenite is also consistent with higher grade metamorphism in this area. The cause of the local high grade amphibolite metamorphism in the eastern lobe of the complex is thought to be due to contact metamorphism from the later granitic intrusions. As mentioned in Chapter II these intrusions surround the eastern lobe on all but the southern margin. Within the grid area small granitic and dioritic dykes were also common. Some additional insight into the metamorphic history of the eastern lobe is provided by the metamorphic plagioclase. It is always fresher than the primary plagioclase, despite its often more calcium rich nature. This relationship indicates that the amphibolite grade metamorphism was superimposed upon a preexisting low grade deuteric or greenschist metamorphism in which the primary plagioclase was often sericitized or sauceritized. The reversed zonation that many of the metamorphic plagioclase grains 115

bit could indicate a progressive increase in tamorphic grade with a quicker drop in temperature

that did not permit homogenization. The metamorphic plagioclase often foims within the cracks in primary plagioclase and lacks any deformational textures. This relationship indicates that the metamorphic plagioclase formed after the complex was folded into its present orientation. This sequence is consistent with contact metamorphism from the post folding granitic intrusions. 116

TER VII PETROCHEMISTRY

The first part of this chapter discusses the

results of whole rock analyses on selected rock samples from the Matagami area. Part two discusses the rare earth element characteristics of some of these samples. Part three discusses the Cu, Ni, Pt and Pd contents of the rock units within the grid area of the eastern lobe of the Bell River Complex.

Whole Rock Analyses Twenty three rock samples were analysed for major elements using the XRF in the Geology Department. The details of the procedure and errors are included in Appendix IIIA. Eleven representative rock samples from the eastern lobe of the Bell River Complex were analysed. From the western part of the area, three Wabassee volcanic samples (28-1, 23-1 and 23-2), a subsidiary gabbro intrusion sample (16-3), and a marginal zone sample (19-2) were analysed (see Chapter V for more details on these samples). Table 11 lists the whole rock analyses together with the rock types and CIPW norms for each sample. Table. 11. Whole Rock Analyses

lagioclase compositions determined on the micro- and from the norm also included. Appendix I ains details on the modal composition of these pies. As expected, there is a good correlation between modal composition and the chemical composition of tte samples. There is also good agreement between .the normative and microprobe plagioclase compositions. Wager and Brown (1968) note that whole rock chemical analyses from a layered series of rocks have limited value in showing changes in the oxides associated with a fractionated series of rocks. This situation is due to the wide variations in the type and proportions of the cumulus minerals and the variable amounts of trapped intercumulus liquid." To minimize these variations, Wager and Brown (1968) suggest that average rocks from a sequence can be used. The trends of these samples will closely parallel the trends of magma change from calculated liquids when plotted on MgO:FeO:(Na2O + K2O) diagrams.

gabbros. The quartz gabbro sample (19-2) plots the closest the alkali corner of any sample in Figure 55. This consistent with its high stratigraphic position in the complex. The large variability of the lamprophyre nA dyke samples is consistent with their variable mineralogy. As expected, the pyroxenites,dunite and peridotite plot far from the "average" gabbros. The volcanic and subsidiary gabbro intrusion samples are plotted in Figure 56 on the Jensen Cation Plot (Jensen, 1976). All four samples are very similar and plot within the high iron tholeiitic field.

Rare Earth Elements Fifteen of the samples that were analysed for major elements were also analysed for rare earth elements (REE). The three Wabassee volcanic samples were analysed to investigate their relationship to the subsidiary gabbro intrusions and to the main part of the Bell River Complex. Sample 19-2 (quartz gabbro) was analysed to see if it could represent a grano- phyre for the complex. In addition, characteristic 124

les from the eastern lobe of the complex were alysed to see if REE trends similar to other ayered intrusions (Kuo and Crocket, 1979) could be le ecognized. The samples were analysed by neutron activation analysis. The details of the procedure and errors are included in Appendix IIIB. Table 12 includes the results discussed in this section and Figure 57 is a plot of these results normalized to chondrite values from Haskin et al. (1968).

Wabassee Volcanics and Subsidiary Gabbro Intrusion Samples

In Figure 57A the three volcanic samples exhibit very similar flat patterns (La/Yb.^ 1.2) with absolute REE abundances about 20x chondrite and negative Eu anomalies. This pattern is similar to other Archean tholeiites such as those from Duparquet, Quebec; Lawlers, Western Australia; Que-Que, Rhodesia; and Minnesota, U.S.A. (Condie and Baranger, 1974; Sun and Nesbitt, 1978). Sample 16-3, from the subsidiary gabbro intrusion, has a very similar pattern to the volcanics.

intrusions in the Matagami area to be subsidiary intrusions of the main Bell River Complex. He also believes that the mafic Wabassee volcanics are comagmatic with the complex. Since a sample from the chill zone of the complex is not available, the possible comagmatic nature of the volcanics and the complex cannot be verified. However, the REE data support a model where the complex acted as the source magma chamber for the mafic volcanics and subsidiary intrusions.

The negative Eu anomalies in the volcanics and subsidiary intrusion samples is consistent with the fractional crystallization of plagioclase which concentrates Eu relative to the other REE (Schnetzler and Philpotts, 1970). The maximum amount of plagioclase which could be removed from a basaltic melt with no Eu anomaly to yield the observed negative anomalies can be estimated from the equation:

Eu-DEu* 1 D (Eu/Eu*) = (1-X) (Kuo and Crocket, 1979)

Using DEu = .48 and DEu* = .04 for an Ab28 plagioclase content (Schnetzler and Philpotts, 1970), the following

results were obtained: 128

These values are not unreasonable considering the feldspathic nature of the exposed Bell River Complex and the possibility that the melts could have been removed from the magma chamber at any stage in its differentiation.

The nearly flat light REE patterns of these four samples is consistent with plagioclase and pyroxene fractional crystallization. Plagioclase tends to slightly lower the La/Sm ratio of the magma, but this can be counterbalanced by pyroxene crystallization. Sun and Nesbitt (1978) estimate that a 4:1 plagioclase to clinopyroxene ratio would be enough to reverse the effect and this ratio is close to that observed in the exposed part of the Bell River

Complex.

Assuming that the parental magma had a flat pattern, the Yb/Gd (< 1) ratio of the four samples in Figure 57A is consistent with the fractional 129

crystallization of orthopyroxene or calcium poor clinopyroxene (Sun and Nesbitt, 1978). If the Bell River Complex was a fractionation chamber for the samples, this data could indicate the existence of an ultramafic hidden zone since these minerals are very rare in the exposed parts of complex. Therefore the REE data don't rule out the possibility that the Bell River Complex acted as a fractionation chamber for the Wabassee volcanics and subsidiary gabbro intrusions. These results, however, can also be explained by a partial melting model in which some plagioclase is residual in the source area to explain the Eu anomaly. The Yb/Gd ratios that are <1 can be explained by residual orthopyroxene, calcium poor clinopyroxene, or garnet in the source area.

Bell River Complex Samples The REE data for most of the samples from the Bell River Complex are erratic (Figure 57B). This is due to the low absolute REE contents in most of these samples and the high detection limits for some elements. The complex sample with the highest absolute REE 130

content is sample 19-2. This quartz gabbro sample has a fractionated pattern with a La/Yb ratio of 2.5.

The high La/Yb ratio and absolute REE content, compared to the other complex samples, make it similar to granophyres in other layered intrusions (Kuo and

Crocket, 1979). However, using the method of Kuo and

Crocket (1978) described previously,only about 21% of an initial magma without an Eu anomaly would have had to crystallize as plagioclase to result in the observed Eu anomaly for this sample. This seems unlikely considering the large percentage of plagioclase in the exposed part of the complex. Also, the high La/Sm ratio necessitates the crystallization of large amounts of pyroxene assuming a flat pattern for the parent melt. This could indicate a lower ultramafic zone for the complex, but a problem arises if the previously described volcanics samples also represent magmas periodically erupted from the Bell

River Complex magma chamber. These samples have much more negative Eu anomalies than 19-2 but they have less fractionated REE patterns. Therefore it seems unlikely that all of these samples have a similar source. Unfortunately, this problem cannot presently be resolved because the exact nature of sample 19-2 131

is in question. It could represent quartz diabase which is noted in the same area by Freeman and Black (1944). No contacts with typical complex rocks were observed to possibly clarify its nature and the REE pattern is not unlike other diabase samples reported by (Philpotts and Schnetzler, 1968; Kuo and Crocket, 1979). Of the remaining complex samples the two pyroxenite samples (T58, 27-17) have the highest REE contents with about 7x chondrite. Although T58 contains a substantial amount of intercumulus inverted pigeonite, no significant differences in the two samples is noted. The negative Eu anomaly in both of these samples is consistent with previous crystallization of plagioclase.

The gabbro samples form a fairly regular group with REE abundances between 1 and 4x chondrite. These abundances are similar to gabbros and norites from the Bushveld and Muskox intrusions (Kuo and Crocket, 1979). Sample T42 has the most regular pattern of the gabbro samples and as expected, has a prominant positive Eu anomaly. Sample T57 is a dunite sample. It generally has 132

the lowest REE content of any of the samples reflecting the small partition coefficients of olivine for REE.

Lamprophyre Dyke Samples Two lamprophyre dyke samples were analysed for REE, but only T-16 is shown in Figure 57B. Sample T82 (see Table 12) has very low and erratic REE values and wasn't included in Figure 57B. Sample T-16 has the highest REE content of any of the analysed samples with 20-80x chondrite. It also has the highest La/Yb ratio at 3.15. Since this sample contains 2% apatite, these values are not surprising. The very low values for T82 indicate a different history from T-16 and suggest the possibility of several stages of lamprophyre dyking in the area.

Cu, Ni, Pt, Pd Contents Selected rock samples from the eastern lobe of the Bell River Complex were analysed for Cu, Ni, Pt, and Pd as part of the exploration work for Canadian Occidental Petroleum, Ltd. In general, 580 rock chips of the various rock types and 92 rocks samples 133

of visibly mineralized material were analysed. Appendix IIIC contains more details on these samples. The samples were sent to Bondar-Clegg and Company, Ltd. where they were ground to -100 mesh. Cu and Ni were analysed by atomic absorption spectrometry after extraction with a hot solution of HC1-HNO3. Pt and Pd were analysed by a combined fire assay-atomic absorption technique. Appendix IIIC contains the analytical results along with a discussion of the precision. Background and anomalous values for these samples were established by grouping the results into fixed ranges and constructing histograms (Figure 58). The histograms were fitted with a bell shaped curve and the high values eliminated from further statistical treatment. Cumulative percentage graphs of the normal populations were constructed and background and anomalous values were selected from these plots at the 50% and 97% levels respectively. There were too few Pt and Pd analyses to use the above statistical method for some rock types. In these cases the arithmetic mean was estimated from the histograms if one interval contained the majority of the samples, or the mean was calculated

assuming L5 was equal to 4 ppb. Table 13 contains the calculated results for each rock type.

There is a very good correlation between the Cu and Ni values and the mafic content of the rocks in Table 13. The higher values in the pyroxenite reflects its consistent sulfide mineralization (see

Chapter III). The low Ni values reflect the rarety of pentlandite and millerite and the low Ni content of the pyrrhotite in these rocks. The Pt and Pd results for all rock types are very low and erratic.

Figures 59 and 60 show the contoured Cu results for the rock chips and rock samples from the grid area. The Ni results show similar anomalous areas and a comparison with the geology in Figures 11 and

12 shows that the mafic rich units 1 and 2 tend to have con- sistently higher values. Both of these units contain magnetite and the most consistent sulfide mineralization within the eastern lobe of the Bell River Complex.

Von Gruenewaldt (1976) notes an association of sulfide mineralization in the Bushveld intrusion with the magnetite layers. He postulates that magnetite crystallization reduces the FeO content of the magma

to the point where sulfides can separate from the

mayiva. Table $3 Metal Content of Rock Types

The unit 1 pyroxenite was chip sampled in more detail at several locations within the grid area. Figure 61 shows the Cu/Cu+Ni ratios from these samples. The sample traverses are arranged in what is thought to be their relative stratigraphic position if tops face to the east. There appears to be a weak trend of increasing average Cu/Cu+Ni ratio of each pyroxenite with increasing stratigraphic height. Similar increases have been noted in sulfide assemblages in the Bushveld intrusion by Liebenberg (1970) and Von Gruenwaldt (1976). This relationship is therefore consistent with other top determinations within this part of the Bell River Complex. 141

CHAPTER VIII SUMMARY AND CONCLUSIONS

Sequence of Events The Bell River Complex is a large layered intrusion of Archean age that intruded the Lac Watson and Wabassee volcanics. The sequence underwent regional low grade metamorphism and was folded into a large east-southeast trending anticline whose axis is approximately coaxial with the complex. This folding caused longitudinal faulting and local brecciation in the Bell River Complex and volcanics. Lamprophyre dyke intrusion occurred during and after the folding and faulting. The folded sequence was then intruded by granitic plutons 2.5 - 2.6 b.y. ago. The intrusion of the Olga quartz diorite divided the Bell River Complex into two separate lobes. A pink granite pluton then intruded the eastern end of the complex. Diabase dykingj 2.1 b.y. ago, was the final intrusive event in this area. The eastern lobe of the Bell River Complex was subjected to amphibolite grade contact metamorphism by the granitic plutonism. This metamorphism resulted in the widespread development of metamorphic plagioclase (albite-andesine) within the gabbros. The original igneous clinopyroxene was replaced by 143

amphibolte + quartz, oriented amphibole grains, or randomly oriented amphibole grains, depending upon the intensity of metamorphism. The present freshness of the metamorphic plagioclase indicates that very little low grade metamorphism occurred after the contact metamorphic event.

Eastern Lobe Structure The structure of the eastern lobe of the Bell River Complex is less clear than in the western lobe because of the granitic intrusions and poor volcanic exposures. The volcanics and sediments south of the eastern lobe appear to be more intensely folded (along east-northeast axes) than in the homocline to the west. Within the eastern lobe, the layered gabbros have north-northeast strikes and moderate to steep southeast dips. This orientation is noticeably different than the east-southeast strike in the western lobe. Top determinations in the gabbros of the eastern lobe of the complex include a crossbedding relationship and cryptic variations in the plagioclase, clinopyroxene, and unit 1 sulfides. All of these indicate that stratigraphic tops are to the southeast in the grid area. Therefore the available data indicate that the eastern lobe of 144

the complex is the eastward plunging nose of the Bell

River anticline.

Relation of Bell River Complex to Volcanics

The Bell River Complex has definitely intruded

the Lac Watson and the lower part of the Wabassee

volcanics. However, the sill like nature of the

subsidiary intrusions and their similarity to massive

volcanic flows indicate that the complex was a

differentiation chamber for some of the later Wabassee volcanics. The Wabassee volcanics and a

subsidiary gabbro intrusion have similar normalized

rare earth patterns which indicates similar source

areas. The rare earth patterns do not rule out the

Bell River Complex as the source magma chamber, but

the data could also reflect residual phases in a

mantle source.

Rock Types and Stratigraphy of the Bell River Complex

The exposed part of Bell River Complex is mainly

composed of medium to coarse grained gabbro with

60-80% plagioclase and 20-40% uralitized clino-

pyroxene. However, a complete range of gabbros from pyroxenite to anorthosite is present along with dunite and peridotite. 145

The western lobe of the complex has been divided into three zones: a well layered, magnetite rich marginal zone; a poorly layered, felsic rich core zone;

and subsidiary intrusions. Aeromagnetic data and

lithological similarities indicate that the southern

marginal zone of the complex is present in both the

eastern and western lobes. The major part of the

eastern lobe appears to correlate with the core zone

in the west.

The stratigraphic interval covered by the grid

area in the eastern Lobe of the complex can

not be defined precisely since a detailed stratigraphy

is not present in the western lobe. However, the

grid area appears to extend from the top of the

core zone through the lower part of marginal zone.

Figure 62 is a schematic stratigraphic column

through the grid area to the southeastern margin of

the complex. The bottom of the marginal zone is

taken at the base of unit 2. The upper part of the

column is speculative because the magnetite bearing

gabbros in the southeastern part of the grid appear

to be faulted against the other complex rocks. The

thickness shown for these upper magnetite bearing

gabbros is taken from the aeromagnetic map and 146 Plagioclase Clinopyroxene Olivine granite 14

represents a minimum since the top of the sequence has been intruded by granites. Within the column in Figure 62, the only units that exhibit conspicuous layering are unit 2 at the bottom and unit 3 near the top. Both of these units contain magnetite + ilmenite mineralization. The olvine bearing facies of unit 2 represents the only known olivine in the Bell River Complex. Poorly layered gabbros that range from pyroxenitic gabbro through anorthosite make up the interval between the layered units in Figure 62. A minimum of two major pyroxenite units occurs within these poorly layered gabbros. This number is based upon the northern half of the grid and assumes, as the pyroxene compositions indicate, that unit 1 in the southern part of the grid is a faulted segment of the east-central zone. The pyroxenites contain uneconomic Cu-Ni sulfides and minor magnetite ilmenite mineralization. The sulfides do not carry Pt or Pd values. The cumulus mineral compositions are also included in Figure 62. The plagioclase generally varies from Ab17 at the top of the core zone to 148

Ab 30 in the upper magnetite bearing gabbro. The clinopyroxene varies from En43.6 Fs7.7 in Wo48.6 unit 2 to Wo49.3 En34.8 Fs15.9 in an upper unit 1 pyroxenite.

Comparison of the Bell River Complex with Other Layered Intrusions Several authors have noted similarities in rock type and structure between the Bell River and Dore Lake Complexes (Naldrett et al., 1970; Allard et al., 1972). The Dore Lake Complex is another large layered gabbro intrusion in the Abitibi orogenic belt near Chibougamau, Quebec (Figure 1). The present work on the Bell River Complex also indicates similarities in these two intrusions. Figure 63 includes a stratigraphic column for the Dore Lake Complex. Allard (1970) considers this complex to be the upper portion of a "Bushveld" type layered mafic intrusion. A comparison with the other intrusions in Figure 63 shows the similarities. The Bell River Complex, like the Dore Lake Complex, has an anorthositic lower zone and an 149

upper magnetite bearing zone. A more detailed

Fig.63 Comparison between the Dore Loke Complex and other important layered complexés showing the basis for postulating a Lower Hidden Zone in the Dore Lake Complex (from Woger and Brown, 1967, and Allard, 1970). (Allard et al.; 1972

comparison indicates that the core and marginal zones

in the Bell River Complex are quite similar petro-

graphically to the anorthosite and layered zones

respectively in the Dore Lake Complex.

The anorthosite zone in the Dore Lake Complex is 150

about 10,000 ft. thick and contains poorly layered, often pegmatitic felsic gabbro (50-100% feldspar). One optically determined plagioclase composition of An80 is reported and the normative compositions range at the top of the from An95 at the bottom to An72 zone (Allard, 1976). Adcumulate textures are common. All of these characteristics are very similar to the core zone in the Bell River Complex. The layered zone in the Dore Lake Complex contains three pyroxenitic members with two inter-

vening felsic gabbro members. The pyroxenite members are finely interlayered pyroxenites and gabbros that contain magnetite + ilmenite mineralization. The felsic gabbro members are poorly layered and magnetite poor. The normative plagioclase compositions in this zone vary from An73 at the bottom to An52 at the top. Several characteristics of the marginal zone in the Bell River Complex are similar to this layered zone. In a general sense, the repetition of pyroxenite with intervening, poorly layered gabbros is quite similar in both cases. Unit 2 in the eastern lobe of the Bell River Complex is nearly identical to the pyroxenitic members of the layered 151

zone. Unit 2a has the same olivine composition and nearly identical texture and original mineralogy as a dunitic facies of the layered zone in the Dore Lake Complex. The plagioclase compositions in the lower half of the marginal zone of the Bell River Complex are similar to the normative plagioclase compositions in the lower part of the layered zone. The presence of quartz and apatite bearing gabbros in the marginal zone of the Bell River Complex is also similar to the upper parts of this layered zone. Although the marginal and layered zones in these two intrusions are very similar, there are two main differences. The Dore Lake Complex does not appear to contain thick and homogeneous pyroxenites similar to unit 1 in the Bell River Complex. More importantly, however, the marginal zone appears to be much thicker than the layered zone in the Dore Lake Complex. This is evident from a comparison of the thickness in Figure 62 (ti 14,000 ft.) with that in Figure 63

(ti 3,000 ft.). Other thickness estimates for the marginal zone of the Bell River Complex are similar to the grid area. The northern marginal zone at the Bell River is about 5,000 ft. thick, but five miles to the east it increases to about 15,000 ft. Part of this increase is due to the intercalation of volcanic rocks and possibly tight folding, but on the homoclinal southern limb of the anticline the marginal zone is also about 15,000 ft. thick. The marginal zone of the Bell River Complex could include material similar to the sodagranophyre and upper border groups in the Dore Lake Complex since outcrop control is very poor in the upper marginal zone. However, even if this is true the total thickness of the layered, sodagranophyre and upper border zones is only about 7,000 ft. or one half the thickness of the marginal zone in the Bell River Complex. The similarities between the Bell River and Dore Lake Complexes indicate that the Bell River Complex is another "Bushveld" type intrusion. Therefore a lower ultramafic hidden zone should be suspected and this could indicate a chromite potential for the area. More importantly, however, the exposed thickness of the core zone is such that a Merensky Reef type Pt horizon could be exposed near the center of the Bell River anticline. Further exploration would seem to be warranted in that area. 153 REFERENCES

APPENDIX II

Electron Microprobe Procedures and Results

This appendix contains the procedures used to analyse the various mineral phases by the electron microprobe.

The results of these analyses are also included.

The majority of the microprobe work was done on an Applied Research Laboratories E. M. X. microprobe using the off-line data reduction program of Smith

(1975). Plagioclase, amphibole, sulfide, oxide, T57 and

25-3 olivine and T59 clinopyroxene analyses were all done on this instrument.

The standards used for these different mineral

phases are as follows:

Silicates CCNM0076 Albite for: Na, Al, Si CCNM0063 Wakefield diopside for: Ca, Mg CCNM0071 Hornfels sanidine for: K, Ba CCNM0102 Biotite for: Fe, Ti, Mn CCNM0010 Cobalt for: Co

Magnetite and Ilmenite CCNM0069 Hematite for: Fe CCNM0162 Rutile for: Tio V CCNM0102 Biotite for: Mn CCNM0010 Cobalt for: Co 177

Sulfides CCNM0081 FNS 107 for: Ni, Fe, S CCNM0010 Cobalt for: Co CCNM0080 Chalcopyrite for: Cu The CCNM number is the identification number used for standards in the University of Toronto reduction program. All minerals were analysed using a 15KV accelerating voltage, a beam current normalized to 3000 c.p.s. and 100 sec. counting times. Plagioclase analyses were carried out by scanning a 5 x 5 micron area to minimize alkali migration. Primary plagioclase analyses 26-1, 26-2, 26-4, 26-5, 15-1, 13-2, 16-1 and the metamorphic plagioclase analyses were also done on the A.R.L., but a 20 KV accelerating voltage was used in conjunction with the on-line reduction program PEST (Stratham, 1976). In this case the beam current was normalized to 3000 c.p.s. only on willemite. Sample T-27 was used as an internal standard to insure conformity with previous results. The majority of the olivine and pyroxene analyses were obtained using an ETEC AUTOPROBE and the PEST reduction program. A 20 KV accelerating voltage along with 100 sec. counting times were used. The beam current was normalized to 3000 c.p.s. only on the willemite standard. This instrument was preferred 178

over the A.R.L. for the pyroxene analyses because of the improved optics which made it possible to locate pyroxene spots in the uralitized samples. The order of the reults for the different minerals in this Appendix is shown below:

primary plagioclase IIA metamorphic plagioclase IIB pyroxene IIC olivine IID amphibole IIE sulfides IIF ilmenite and magnetite IIG 179

APPENDIX IIA

This appendix contains the individual analyses on primary plagioclase feldspar. The results are summarized in Table 4,Chapter VI. In order to minimize any compositional variations between sample runs, all runs have been normalized using sample T-27 as an internal. standard. Two of the early runs using the off line reduction program were found to need corrections as indicated in Table l4. The normalized results are plotted in Figure 48, Chapter VI. 180

APPENDIX IIC

This Appendix contians the microprobe results for the pyroxene analyses. The results tabulated in Chapter VI are taken directly from these results except for the samples on L160N where the following adjustments were found to be necessary. Table 15 summarizes the initial energy dispersive electron microprobe data for the pyroxenes on L160N. Samples 27-1 through 27-5 are statistically the same. Then there is a noticeable compositional break and samples 27-6 through 27-8 are similar. The break in the results between samples 27-5 and 27-6 was thought to be due to different probing sessions and not to an actual change in the pyroxene composition. Therefore samples 27-5 and 27-6 were reanalysed on the ARL. The results are included in Table l5 labelled (checks. The new results for sample 27-5 agree well with the previous results, but the Ca in the new 27--6 results is noticeably lower and Mg is higher than before. In order to gauge relative changes in the pyroxene composition across unit 1, the initial mean values for samples 27-5 and 27-6 were adjusted to 208

This appendix contains the procedures and details relating to the petrochemistry of the rocks. The three sections of this appendix are:

Whole Rock Analyses IIIA Rare Earth Element Analyses IIIB Cu, Ni, Pt, and Pd Analyses IIIC

APPENDIX IIIA

Twenty three samples were analysed for major elements on the XRF in the geology department. The FeO in these samples was determined by titration with potassium di- chromate. Loss on ignition was done by heating a 1 gm. sample for one half hour at 1075°C within a pure nitrogen atmosphere. The sample preparation was carried out according to the procedure of Norrish and Hutton (1969). Each analysis was performed in duplicate and the average values are presented in Table 11, Chapter VII. For a discussion of the instrumental precision and the accuracy of the method see Gorton et al. (1979). 228

! APPENDIX IIIB

This Appendix contains the procedures used to analyse the samples for REE. Approximately 300 milligrams of each sample was weighed out and sealed in plastic viles. These samples were irradiated overnight in the Slow Poke Reactor at the University of Toronto. After a seven day cooling period, the first count was done on the equipment at Erindale College. A second count, usually done 40 days after irradiation, had to be carried out slightly later because of instrumental difficulties. The observed elemental peaks and counters used for these counts are shown in Table 16. The results of these counts were convereted to ppm in the sample using the formula:

ppm - peak_ counts/live time e X t• wt • F

where a - In 2 half life t = time between sample and standard F = factor for element when solving this equation for F using the accepted ppm. Nim-G was used as the standard for all elements except Eu where UTB-1 was used with a value of 2.06 ppm. The 229

*1 to correct for an U interference in the Nim-G standard with this peak, 12% was added to the ppm calculated.

*2 to correct for an U interference in the Nim-G standard with this peak, 6% was added to the ppm calculated.

*3 Tb has an interference from a Pa peak at 300 KeV. To correct for this, 17.67% of the Pa peak at 311.9 KeV was calculated and subtracted from the Tb-Pa doublet at 298-300 KeV. 2310

accepted values for Nim-G were taken from Jackson and Strelow (1975). Table 17 includes the results for the samples along with detection limits that were calculated using the method of Kruger (1971). Only those values which are greater than or equal to the detection limits are shown in Table 12, Chapter VII. The Ho and Gd values are not included in Table 12 because initial chondrite normalized plots indicated that these elements were too low. Rlthough the samples were crushed in a tungsten carbide mill, the chondrite normalized Lu results look satisfactory. Therefore, despite the interference of a tungsten peck with Lu, the results are included in Chapter VII. Two samples of Nim-G and UTB-1 were analysed with the unknown samples. One of the Nim-G samples was used as a standard and the other analysed as an unknown. Table 18 shows the results for these samples along with the percent differences from the accepted values and, in the case of UTB-1, the coefficient of variance. Table 17.

Brief field descriptions of the samples are also included. In order to access the analytical precision of the results, standard soil samples were sent with each series of samples. The results for these standards are shown in Table 19. The Pt and Pd values included in this appendix were taken directly from the reports of Bondar-Clegg and Co. Ltd. to Canadian Occidental Petroleum Ltd. Bondar- Clegg was contacted in May of 1980 to clarify the difference between N.D. and 45. At that time they gave detection limits of Pt=15 ppb and Pd=2 ppb. Therefore all quoted Pt values which are less than 15 ppb or N.D.

should read 415 ppb and all quoted Pd values of (5 and N.D. should read <. 2 ppb. 234

APPENDIX IV

A ground magnetometer survey was conducted on the property to help extend lithologies into covered areas. Two magnetometers were used in this survey. A Geometrics Unimag G-836 was used for the first part of this survey and it had a sensitivity of 10 gammas. This magnetometer was on loan from Exploranium Corpôration until the company's was repaired. The survey was completed with a•Geometrics Model G-816. Although this magnetometer had a sensitivity of 1 gamma, readings were rounded to the nearest 10th gamma so that they would have the same sensitivity as the ones taken earlier. Both of the magnetometers which were used measured the total intensity of the earth's magnetic field. Survey Procedure Base stations were established on BLO+00 every 400' up to 80N and on TL47+00 from 80N to 212N. Measurements were taken every 100' on each grid line on the property. If anomalous values were obtained, readings were taken at 50' intervals until the anomaly was passed over. All values were corrected for diurnal variations by frequent returns to base stations.
