ABSTRACT

The Precambrian basement In southern Ontario is part of the Canadian

Shield and is overlain by Paleozoic rocks with a maximum thickness of

1AOO m. The basement physiography is dominated by a northeast-southwest

paleotopographic ridge which is made up of the Algonquin Arch and the

Findlay Arch. These arches are separated by a low lying area called the

Chatham Sag. The arch system also separates two Paleozoic basins -the

Michigan Basin and the Appalachian Basin.

The evaluation of drilling records for 563 holes that penetrate the

Precambrian basement has been used to produce a structural contour map

of the basement surface, which outlines the shape and size of the arches

and also identifies the existence of some smaller paleotopographic highs

and lows. Samples of basement rocks for 341 holes for which samples

exist have been examined petrographically, chemically and magnetically

to identify the rock type and produce a lithological map for buried

Precambrian basement. I-ferr^s-esjCiaiated that- J2ie rock type distribution

for the basement is: granite and syenite gneiss 67%, granodiorite gneiss A 4%, metagabbro 32, clastic metasedlmentary rocks 182, marble 72, other 12.

No evidence has been found to indicate the presence of metavolcanic rock.

Magnetic anomaly patterns indicate regional trends are northeast-southwest

4 as is the general trend in the exposed Grenville rovince. The tectonic subdivisions of the Grenville can be projected to the subsurface.

THE GEOLOGY OF THE PRECAMBRIAN BASEMENT IN SOUTHERN ONTARIO by A. Turek and R.N. Robinson 1984 INTRODUCTION

Southern Ontario (Fig. 1) is underlain by Paleozoic rocks which are up to 1400 m thick, and have been deposited unconfonnably on a Precambrian basement. This basement is the continuation of the Canadian Shield. Drilling records exist for approximately 15,000 wells that have been drilled in southern Ontario over the last 70 years, principally in connection with oil and gas exploration and exploitation. Of the above wells there are about 1,200 that penetrate the Cambrian and Ordovician strata and 563 wells that penetrate the Precambrian basement. The wells that penetrate the basement provide information on depth to basement and also provide samples, in the form of cores and chips, of the Precambrian rocks. The objectives of this study were to produce a structural contour map of the buried Precambrian surface and also from the examination of core and chip samples to produce a lithologic map of the buried Precambrian shield.

Well log records and drill hole samples are kept by the Petroleum

Division of the Ontario Ministry of Natural Resources in London. From the well log records information was abstracted for all holes that pene trate the basement. Information on the location of the hole, collar elevation, and depth to basement was used to construct a structural contour map for the Precambrian surface, which is Map l (in pocket).

Samples, as cores and chips, are in storage for 341 of the holes that penetrate the basement. There are core samples for 19 holes and chip samples for the rest of the holes; the average basement penetration is 11 m. All samples of basement rocks were examined under a binocular l University of Windsor, Windsor, Ontario.

D*© 3 microscope to identify the rock type. In addition 49 thin sections and 59 chemical analyses were used to further assist in the rock type iden tification. For the chip samples thin sections were made from an epoxy mount of the chips. For the purpose of producing a lithologic map of the basement the number of rock types was reduced to the following broad categories: granite gneiss, syenite gneiss, granodiorite gneiss, metagabbro, amphibolite, clastic metasedimentary rocks and marble. The dis tribution of granitic and syenitic gneisses is very intermixed, but the other rock units occur in discrete areas and form mappable units. Measurement of magnetic susceptibility on selected chip samples and examination of a magnetic anomaly map for southwestern Ontario were also used in the preparation of the lithology map. The distribution of the different rock units was assigned chiefly on the basis of drill hole sample identification. The lithology map is May 2 (in pocket). There has been no previous systematic and comprehensive study of the Precambrian basement in southern Ontario. Definitive work on the geology of southwestern Ontario is that of Bringham (1971), which is primarily concerned with the Paleozoic rocks, but it discusses the Precambrian structural features and gives a structural countour map of the basement. A magnetic survey for southwestern Ontario was done by Nwachukwu (1964) and provides a magnetic anomaly map of the basement. Robinson (1980) produced the first lithologic map for the basement in the Windsor, Chatham, Sarnia region; based on the examination of drill hole samples. Essentially this was a pilot study for this project. A lithologic map of the buried Precambrian basement in Michigan, based on geophysical data was produced by Kellog (1971). ACKNOWLEDGEMENTS

WeU Log Piles Records containing information for approximately 15,000 wells

drilled in southern Ontario are kept by the Ministry of Natural Resources in London. Prom these records information was abstracted regarding those well holes that penetrate the Precambrian basement.

Computer Methods \ An Apple II+ micro computer was used to enter information on all basement holes. The information recorded was as follows: 1) Name of well [ 2) County and Township wherein well was located ^j? .J1 - L A \SA l 3) Longitude and latitude of above .© jr ,. \ 4) Collar elevation (above mean sea level) 5) Depth to basement and penetration 6) Sample tray location number 7) Comments, e.g., rock type, if recorded. This data file is listed In part in Appendix A. Originally infor mation on 603 holes was extracted from the well log files. Some of the holes recorded were known not to be basement holes but were considered useful for minimum depth control. However j there were some duplicate entries and some holes that were subsequently found not to be basement holes. When these werei eliminated the file contained a listing of 563 holes that pen e tr a t eCv the basement. A computer file was invaluable in selective retrieval of data. 6

It was possible, for example, to retrieve hole information by County, longitude and Latitude, which was helpful in the plotting of the hole location. The well log files contain information in both imperial and metric units, this was standardized to metric. To help locate the samples the sample tray numbers were arranged consecutively which greatly expedited the search for samples in the core racks. The mar ginal notes for Map l (in pocket) were prepared from this file.

The examination of core and chip samples and the identification of the rock type was recorded and formed a second data file. This is given in Appendix B, which contains rock types for 341 holes for which samples were available.

Structural Contour Map The holes that penetrate the basement were plotted on 1:250,000 NTS t: base maps. The depths to basement were contoured to produce the struc tural comntour map for the Precambrian surface (Map l , in pocket) . - Though there are 563 holes to basement, Map l is based on 519 holes. It was not possible to locate some of the holes accurately, as there have been changes in township boundaries and the old maps are no longer available, also the records did not contain longitude and latitude locations.

Lithology -

The lithology map (Map 2, in pocket) is based on the identification of basement samples for 341 holes, for which samples exist in the core lab of the Ministry of Natural Resources in London.

Core and chip samples were examined under a binocular microscope to identify the rock type. Thin sections were prepared for 49 samples 7

to confirm rock identification. For chip samples thin sections were made from an epoxy mount of the chips. Of the 341 holes for which samples are available only 19 are core samples - all other are chip samples. In addition to thin sections 59 samples were chemically analyzed for major and trace element content. The rock type identification is given in Appendix A and B, and the petrographic description in Appendic C. Drill logs for holes where more than one rock type was identified, and there was sufficient sample material present, are given in Appendix D. The chemical analyses are listed in Appendix E. Rock type identification of core samples, especially with the aid of a thin section, is relatively easy. On the other hand the identifi cation of rock type from chip samples is more difficult. However, chip samples are actual rock fragments and not individual mineral grains. In identifying clastic metasedimentary rocks the presence of rounded quartz grains was considered a diagnostic criterion. Chemical analyses were a further aid here. For example, high CaO and low Na-0 and K-O are character

istic of metasedimentary rocks. The areal distribution assigned to the different rock types as shown on Map 2 is ^"arbitrary. Most of the boundaries are mechanically drawn in a manner similar to the drawing of contours. The large metasedimentary areas, based on several drill hole intersections, are thought to be of reasonably reliable dimensions. However, those areas based on one hole are obviously speculative. The magnetic anomaly map of Nwachukwu (1964) supports the existence of certain rock types, such as gabbroic and vfcy" metasedimentary rocks, it is, however, not/rielpful in outlining the extent of such rocks. 8

Magnetic Susceptibility Magnetic susceptibility of most of the chip samples was measured using a Bison 3101A instrument. The results are given in Appendix B. The purpose of this measurement was to obtain another parameter that would be a diagnostic of the rock type. There is a correlation between ynlgerclj ^ the mafic/content of trkie rock and its magnetic susceptibility. But, petrographic examination is considered to be a preferred method of rock identification. Nevertheless, the magnetic susceptibility may prove useful and relevant to subsequent surface or airborne magnetic surveys. BASEMENT STRUCTURE AND PHYSIOGRAPHY

The structural and physiographic features of the Basement that can be deduced from the depth to basement information from 519 holes are es sentially large scale features. The examination of drill core samples shows that most rocks are gneissic. The foliation has an average dip of 500 , but ranges between 30 0-80 0 . Presumably the trend of foliation is northeast as would be expected for this part of the Precambrian shield and it is also the dominant trend of magnetic anomalies as shown by Nwachukwu (1964). Major folds cannot be outlined by the distribution of the different rock types. There is, however, a northeast-southwest trend to the distribution of the metasedlmentary rocks.

Algonquin and Findlay Arch System The dominant feature of the Precambrian basement is a northeast- southwest topographic high which is made up of the Algonquin Arch and the Findlay Arch. Fig. 2 is a summary of the major features of the Precambrian basement. The Algonquin Arch extends from the exposed Precambrian shield north of Lake Simcoe to about Chatham. The Findlay Arch extends from the Ohio-Michigan border in the United States also to about Chatham. These arches separate two Paleozoic basins, the Michigan Basin to the northwest and the Appalachian Basin to the southeast. The Chatham area between the two arches is commonly known as the Chatham Sag, and the maximum depth to basement is -1200 m below sea level. The arch system has been recognized as early as 1854 by William Logan. Bringham (1971) has summarized some of the views on the origin zCO l 4* 9

CM O a d s

O 11 of the arch system. There is no concensus with regards to the age and origin of this feature, it may be a Precambrian topographic remnant, or be the result of subsidence of the Michigan basin and could be penecon temporaneous with Paleozoic deposition, or a combination of both. How ever, the distribution of the Cambrian rocks as shown by B r ing ham (1971) show Cambrian isopach lines controlled by the Algonquin Arch where no Cambrian sediments exist, but the Findlay Arch, which is a deeper feature, is covered by Cambrian deposits. The next stratigraphic unit, Upper Ordovician Trenton-Black River groups no longer appears to reflect the basement features, the isopach lines trend northeast-southwest and thus it appears that Ordovician deposition was controlled by the outline of the Michigan Basin. The shape of the arches as shown in Fig. 2 is defined by the -875 m and -975 m contour lines. These are the lowest (i.e., greatest depth) contour lines that show the closure of the arches. This outline of the shape of the arches is different from that given by Bringham (1971).

Topographic Highs and Lows Fig. 2 identifies several paleotopographic highs and lows. These- are as follows: M y 1. Salem tarlgh, at -250 m below sea level is a 400 m high promon tory, relative to the surrounding paleotopgraphy, and is outlined by the -400 m contour. This high is postulated from 4 holes. The western side of this high shows a steeply dipping surface and this may be a fault.

2. Kincardine ^ gh is at -300 m below sea level and relative to X \ the surrounding terrain it is 400/m high. The existence of this high is postulated from only l hole, and hence reliability is .uncertain. It may be part of the Salem high separated by an erosional valley or a fault g r abb en. Ux 3. Strathroy /LOW is the deepest depression in the study area at -1200 m below sea level and relative to surrounding terrain it is a -325 m depression. Evidence for this is only l hole. Adjacent to this, contour intensity trending northeast, based on 4 holes, may indicate the presence of a fault scarp having a northeast-southwest trend. 4. Gosfield iflgh^ is minor 25 m high area on the Findley Arch. fr ©H 5. Brantford ^jfi-gh is at -400 m below sea level and it is about 0s0 200 m above surrounding terrain. It is based on 2 holes. 6. Hamilton 2bw is at -775 m below sea level and it is a 225 m depression, based on l hole.. 7. Edwards hlow is at -775 m below sea level, relatively it is a 100 m depression based on 4 holes. However, this area is sparsely drilled and hence reliability for this feature is low. ^ ^ f/ The Salem ^(igh, Strathroy ^w and the Electric lault are shown in plan view and in cross section in Fig. 3 to Fig. 9 (the rock types shown on the cross sections are pattern coded as in Fig . 10) .

LAKE ST.CLAIR

Fig. 9. Map of geology in the area of the Electric Fault. This map is redrawn from Map 2 (in pocket) to show the apparent sinistral 3 km displacement of the body of clastic metasedimentary rocks (6a) along the fault. 20 j occupies the Chatham Sag, which may have formed as the erosional ex- ( l\ pression of the fault. The Electric Fault extends from Lake St. Glair east to Lake Erie. Maximum vertical displacement on the fault, as determined from Paleozoic rocks, is 100 m, therefore as a Precambrian fault 100 m would be the minimum displacement. This fault was previously i thought to be a normal fault with no horizontal displacement, ©but the i geological map Fig. 9, shows a possible sinistral movement along the fault of approximately 3 km as can be seen by the displacement of the i body of clastic metasedimentary rocks. This area is penetrated by 6 holes very close to the fault and the apparent displacement of the metasedimentary body is considered to be well documented. Of course, f it must be acknowledged that the left handed movement on the Electric -f .fault shown in Fig. 9 could be the result of normal faulting depending ! i on the dip of the metasedimentary rocks. This is the only instance in ; . .1 this study where a fault can be recognized by an apparent displacement j of the rocks. The Clearville Fault Block is a horst bounded by two , subvertical normal faults striking N110W, with a maximum vertical dis placement of 60 m, measured by the displacement of Paleozoic rocks. (

The Dover Fault, presumed to be a reverse fault, strikes N720 W and dips - 500 S. Vertical displacement is 25 m to 35 m, again as inferred from displacement of Paleozoic strata. These faults were initially identi- , fied in Paleozoic rocks and extended into the Precambrian. The faults are thought to be Precambrian in age, with periods of movement during j

Paleozoic time. The faults are shown in Fig. 2. The Clearville horst and the Dover fault do not show up as topographic features on the J 21 basement surface probably becausef- the drilling information is insuffi-- i cient. However, the Electric/fault is a linear topographic feature on ^^ the basement surface. The linear trend and high density of the contour lines adjacent to V* the Salem^igh (Fig. 3 and Fig. 4) and the Strathroy Low (Fig. 5 and Fig. 6) , leads to the speculation that these linear features may be fault related. Cross sections (Fig. 4 and Fig. 5), when compared with, the cross section for the known Electric fault (Fig. 7 and Fig. 8) , show a significantly larger topographic expression. However, it must be re cognized that these features may be erosional in origin. For example, the depression separating the Salem and Kincardine highs (Fig. 4) could possibly be a graVben but it could also be a river eroded valley. Part of this area is composed of metasedimentary rocks which may have been differentially eroded.

GEOLOGY

There are 341 holes that penetrate the basement for which samples are available, 19 of these are core samples, the rest are chip samples. Several holes have intersected more than l rock type, consequently 406 rock type identifications was made in this study. The frequency of the different rock types is as follows: granite 422, syenite 252, granodi orite 42, gabbro 32, clastic metasedimentary rocks 182, marble 72, other *^12. The above frequency is probably a good estimate of the areal dis tribution of the above rock units.

Precambrian Regolith

Basement core samples examined show weathering from 3 cm to 3m. There is a direct correlation between the amount of mafic minerals in the rock and the thickness of the regolith. It is therefore inferred that the regolith is an in situ weathered product and can be called a saprolith. This type of weathering would be expected in regions of tropical weathering. Irving (1979) reports paleolatitudes for the Grenville province based on paleomagnetic evidence. The data for the period 950 Ma to 600 Ma indicates an average paleolatitude of 270 -9 and therefore supports the observation that the weathered Precambrian surface * formed in a tropical climate.

Rock Types For the purposes of this study the various rock types identified, as listed in Appendix A and B, have been grouped into 7 units as follows:

Map Rock Unit Compos it ionally equivalent to 1. Granite gneiss

2. Granodiorite gneiss Granodiorite,. tonalite

3. Syenite gneiss Syenite, quartz syenite, alkali feldspar syenite, quartz alkali feldspar syenite, monzonite, quartz monzonite 4. Metagabbro Gabbro, quartz gabbro, diorite, quartz diorite, monzogabbro, quartz monzogabbro, anorthosite, quartz anorthosite 5. Amphibolite Amphibole rich rock with minor feldspar, biotite, quartz 2.4

Map Rock Unit Compos i tionally equivalent to 6a. Clastic metase- sandstone, arkose, greywacke, argillite, sedimentary rocks quartzite, schists. 6b. Marble pure to impure crystalline carbonate rocks, may contain Ca and Mg silicate minerals.

The igneous and crystalline silicate metamorphic rocks are classified according to the quartz-alkali feldspar-plagioclase ternary diagram of Streckeisen (1973) shown in Fig. 11. It must be recognized that there is a semantics problem in naming the basement rocks as textural features and contact relations of the rocks are not known in most cases. A rock having the composition of a granite may be a plutonic Igneous rock or may be a metamorphic rock of undeter- minate origin. This study has adopted metamorphic rock terminology, but this does not preclude the possibility that there are true intrusive rocks in the basement. While foliation and gneissosity are widespread, several unfoliated granite, syenite and gabbro samples have been observed. In the examination of drill core samples a total of 170 m of core has been seen. With few exceptions the rocks are foliated, varying from poorly developed preferred orientation of mineral grains to well developed schistosity or gneissose banding. Foliations in the cores dip between 3O0 and 800 to the core axis with an average dip of 500 . These foliations probably trend in a northeast direction, since magnetic anomalies (Fig. 12) in the study area generally trend northeast, and the regional trends for most of the Grenville province are northeast.

Slickensides have been observed on joint surfaces in holes #38, //39, and //114. The slickensides are parallel or subparallel to the core axis, 25

Fig. 11. Basis of classification for crystalline silicate rocks, as used in this study. The rock units are: granite gneiss -l, l 1 , 2, 3©; syenite gneiss -6, 6©, 7, 7©, 8, 8 f ; granodiorite gneiss - 4, 5©; metagabbro -9, 9 1 , 10, 10*. (Based on Streckeisen, 1973). 26 and may be related to faulting in the vicinity of these holes. Holes #38 and #39 are in close proximity to the Clearville Horst, and hole #114 is close to the Electric Fault. The core from hole #39 also con tains a zone of mylonite l m thick, parallel to the foliation in the rest of that core.

Granite-gneiss Granite-gneiss is the most commonly observed rock type found in .the study area. 165 holes intersect granite gneiss, 159 at the Precambrian surface, comprising 462 of the holes in this study. Unlike other rock types mapped, the granitic rocks are not of local distribution, but are found dispersed over the entire map area. Hole #603 intersects 84 m of albite granite, very homogeneous except for small mafic portions which may be xenoliths. The average modal mineralogical composition of the granitic rocks observed is as follows: quartz 302, alkali feldspar 542, plagioclase (An 04 - An 14) 112, biotite 42, hornblende 12. The granitic gneisses in hand samples are orange-pink to grey in colour. Grain size is medium (2 mm - 4 mm) to coarse pegmatitic. Most samples are foliated, the foliation varying from poorly developed orien tation of mafic minerals to gneissose migmatitic banding. Migmatitic granites are composed of dark layers (10 cm.- 30 cm thick) rich in biotite and amphibole alternating with light coloured mafic Deficient layers of the same thickness. Pegmatitic granites observed in cores are dikes 1.5 m in thickness, cutting the foliation at a small angle. The pegmatite dike from hole #538 contains large grains of magnetite 2 cm - 3 cm in size. Many of the chip samples observed contained rock fragments which show no 27

foliation. Foliation in core samples dips between 30" and 800 . In thin section the granitic gneisses are composed of quartz, orthoclase, microcline, plagioclase (An 04 - An 14), biotite and horn blende. Accessory minerals are muscovite, apatite, epidote, zircon, calcite, and opaque minerals. Textures are allotriomorphic granular to hypidiomorphic granular, medium grained. There were no porphyritic samples observed. Several thin sections show alteration of biotite and hornblende to chlorite and alteration of plagioclase to sericite.

Syenite Gneiss Syenite gneiss, like granite gneiss, forms a major portion of the rocks observed in this study. 92 samples have been identified as syenite, comprising 74J5 of the holes in this study. For the purpose of simplifi cation, syenitic gneisses in this discussion include rocks compositionally equivalent to monzonite* (fields 8 and 8 f in Fig. 11). There were no feldspathoidal syenites found in the study area although these rock types are not uncommon in the exposed Central Metasedimentary Belt of the Grenville province. The average modal mineralogical composition of the syenite gneisses observed is as follows: quartz 122J, alkali feldspar 67%, plagioclase (An 08) 162!, biotite 4Z, hornblende 12. As .hand samples syenitic gneisses are typically red-orange to pink in colour. Grain size is medium (2 mm - 4 mm). Foliation is poorly developed to absent in core samples. In thin sections the essential components of the syenitic gneisses observed are orthoclase, microcline, plagioclase (An 08), quartz, bio tite, and hornblende. Accessory minerals are apatite, calcite, and 28 zircon. Hole //115 contains a quartz monzonite gneiss that has been almost completely altered to kaolinite and sericite, making identifi cation of feldspars Impossible. Textures are allotriomorphic granular to hypidiomorphic granular, medium grained. Sample #115 is cataclastic

allotriomorphic granular; quartz and feldspar grains are Jbigl* fractured

and biotite grains are bent.

Granodiorite Granodioritlc gneiss is not an abundant rock type in the study area. Only 15 holes intersect this rock unit, 13 at the Precambrian surface,

comprising 4% of the holes in the study. For the purpose of simplifica tion, rocks compositionally equivalent to tonalites have been grouped together with granodiorites (fields 4 and 5 in Fig. 11). The granodio rite gneisses tend to occur in small localized areas as can be seen on the lithology map (Fig. 10). The average modal mineralogy of granodioritic gneiss is as follows: quartz 2935, alkali feldspar 14%, plagioclase (An 19) 49%, biotite 3%, hornblende 5!fc. The two other occurrences are insufficiently covered by drilling to prove or disprove this relationship,

Granodioritic gneisses observed in hand samples are pink to grey in colour. Grain size is medium to coarse (2 mm - 10 mm). Foliation is well developed in most samples due to the alignment and/or concentration

of mafic minerals into gneissic layers. Foliation dips range between 400 and 700 .

In thin section the essential minerals of the granodiorite gneisses are quartz, plagioclase (An 18 - 20), microcline, biotite, and hornblende, Accessory minerals are calcite, apatite, zircon, and magnetite. Texture 29 is allotriomorphic granular, medium grained.

Metagabbro Metagabbro and allied rock types are intersected by 7 holes, and constitutes 12 of the holes in this study. Gabbro in this discussion includes dlorltes and anorthosites, and covers fields 9, 9 f , 10, and 10© in Fig. 4. The occurrence of gabbro appears to be spatially related to the clastic metasedimentary. rocks. These occurrences show up as magnetic highs on the magnetics map (Fig. 11). The lithology map (Fig. 10 and Map 2, in pocket) shows 6 areas of gabbro, 4 of which are adjacent to bodies of metasedimentary rocks. The average modal mineralogy of the metagabbro in this study is as follows: quartz 92, alkali feldspar 32, plagioclase (An 18) 74Z, biotite 132, hornblende 12. In hand samples the metagabbro is grey to black in colour. Grain size is medium (2 mm 4 mm). Foliation is absent or poorly developed in core samples. In thin section the essential components of the metagabbros are plagioclase^(An 18), orthoclase, quartz, hornblende, and biotite. Accessory minerals are apatite, sphene, zircon, epidote, and micro cline. Textures are hypidiomorphic granular, medium grained.

Amphibolite Amphibolite was encountered in only 3 holes (#17, #410, #573) which are widely separated from each other. The amphibole content is variable but high, 452, 752, 902 respectively. These rocks could be called horn- 30 blende gneisses as they also contain plagioclase, biotite, and quartz. It is thought as unlikely that these amphibolites may represent mafic metavolcanic rocks because ot their very limited distribution and com position. The average modal mineralogical composition is as follows: quartz 52:, plagioclase (An 20) 122, biotite 1021, amphibole 69%, garnet 4J&. Amphibolite hand samples are dark green to black in colour. Grain size is fine to medium (0.5 mm to 2 mm). All amphibolite samples ob served are chip samples, thus foliation dips are indeterminate. Folia tion in Individual rock chips is well developed in sample #410, absent in sample #573, and moderate in #317. Essential components of ampnibelites as seen in thin sections, are amphibole, plagioclase (An 17 - An 22) biotite, quartz, and garnet. Accessory minerals are calcite and opaques.

Clastic Metasedimentary Rocks

Clastic metasedlmentary rocks are the third most abundant rock type in the map area. Of the 63 holes that intersect these rocks, 56 are sandstone, arkose, argillite, and quartzite, and 16 are biotite chlorite schists. The areas of metasediments show up as magnetic lows on the magnetics map. There are two large metasedimentary areas north of London

(Fig. 10), the northern one corresponds to a magnetic low, while there is no magnetic survey that covers the southern area. It may be that these two areas are contiguous, however, there are three holes that intersect granite and one hole that intersects gabbro lying between the two meta sedimentary bodies. There are several other smaller bodies of metasedi- 31 mentary rocks which form a linear pattern just north of Lake Erie, and may be remnants of a metasedlmentary belt that extended from St.

Catherines west to Erieau and Wallaceburg. The average modal mineral ogical composition of the metasedlmentary rocks is as follows: Quartzite - quartz 962, alkali feldspar 22, plagioclase 12,

biotite 12. Arkose - quartz 532, alkali feldspar 302, plagioclase 62, biotite 52, amphibole 22, chlorite 41. Schist - quartz 282, alkali feldspar 172, plagioclase 42, biotite

312, amphibole 52, chlorite 122, garnet 12, phlogopite 22. The appearance in hand samples of metasedimentary rocks is variable. Metasandstones are generally pink-orange and fine grained (0.5 mm to l mm). Metaarkoses are pink-brown and fine to medium grained (l mm to 4 mm). Metaargillites. are blue to grey-black and very fine grained

(0.5 mm). Quartzites are light green to orange to white, fine to medium grained (l mm to 5 mm). Schists are dark brown to black, with a well developed schistosity and in many cases rounded quartz grains between laminae of biotite and chlorite. Sample #3 is a calcareous sandstone with 10Z glauconite. Sample #211 is a white quartzite overlying or cut by a quartz vein containing minor amounts of sphalerite and pyrite. For thin section descriptions of the metasedimentary rocks see Appendix C.

Marble Marble was intersected in 30 holes. The distribution of the marbles is closely related to the distribution of clastic metasedimentary rocks (Fig. 10). One large area of marble runs north from Brantford up to Guelph. Two other areas of marble were delineated, one near Sarnia lies 32 on the eastern side of a body of clastic metasediment s, the other is located just north of Markham and may be an extension of a belt of. marble that lies to the north-east in the exposed Grenville Province.

Marbles, as hand samples, are generally white, coarse grained (4 mm to 15 mm) mineralogic ally calcite and /or dolomite. Impure marbles are generally finer grained and green or pink in colour. Sample #390, a core from Hastings county, shows well developed sedimentary banding dipping at 5O0 to core axis. Minerals identified as minor constituents in the marbles are diopside, phlogopite, muscovite, graphite, apatite, quartz, and pyrite. Sample #572 contains a large amount of© quartz and alkali feldspar, possibly the result of contamination by caving of the hole. Sample #398d is composed of diopside, plagioclase (An 14), biotite, hornblende, quartz, and calcite, and may be the product of granulite facies metamorphism of an impure calcareous rock (Jackson, 1970). This sample is overlain by marble. The essential components of the marbles as seen in thin sections, are calcite and/or dolomite. Accessory minerals are diopside, apatite, muscovite, epidote, phlogopite, quartz, plagioclase, orthoclase, graphite, and pyrite.

Chemical Analysis 59 samples were analyzed for major, minor and trace element con centrations by argon plasma emission, plus loss on ignition. The results are given in Appendix E. Average major element concentrations for each rock type are not significantly different from the established averages. Slight devia- 33

tlons from the averages can be seen In lower SiO. concentrations and higher CaO and MgO concentrations. Loss on Ignition Is also high In most cases, Indicating contamination of the sample by Paleozoic lime stones and dolomites due to caving of the hole during drilling. Ab normally high AJ-9^3 contents are attributed to contamination of the sample by shale fragments. Consistently low values were obtained for

Co, Cd, Mo, and Sb. There are no anomalous Cu, Ni, Co, values obtained for the gabbro samples analyzed, and no Cu or Mo anomalous values were obtained for the granite and granodiorite samples analyzed. The high Zn concentration (204 ppm) in sample 449b, a marble, is of interest and may indicate possible zinc mineralization.

Magnetic Characteristics of the Basement

Nwachukwu (1964) produced a magnetic anomaly map for southwestern

Ontario, which reflects the geology of the basement. This map was pro duced in part from compilation of previous surveys and there is great variability in the detail of the different surveys. Nevertheless, the magnetics map, Fig. 12, shows a northeast-southwest structural trend

characteristic of the Grenville province. There is good correlation between magnetic highs and the occurrence of gabbros, also there is some correlation between magnetic lows and occurrence of metasedimentary rocks. However, it has been found that the magnetic anomaly is not help ful in locating rock type boundaries. As an aid to identifying rock type from chip samples the magnetic susceptibility of the chip sample was measured. The results are given Pig. 12. Magnetic anomaly map, simplified after Mv:ach.ukr.ni (1964). Contour inter-ral is 100 35 in Table l, Fig. 13 and Appendix B. There are some apparent differences in magnetic susceptibilities between the different rock types but in practice this does not appear to be a diagnostic method of rock identi fication. However, this data may be useful for subsequent magnetic surveys.

Age of the Basement Isotopic age determinations indicate that the basement belongs to the Grenville province, however, in the subsurface as well as in the exposed part of the Grenville older survival ages exist. Wanless jet al. (1965) reports 2 K-Ar biotite ages of 920 Ma and 895 Ma for basement samples from Brant and Kent Counties. For the basement in southern Michigan and northern Ohio Lidiak et aJL (1966) reports 8 biotite ages by K-Ar and Rb-Sr which range between 840 -970 Ma. Basement samples from Manitoulin Island dated by Van Schmus et al. (1975) give a Rb-Sr isoch- tron age of 1454 Ma and a U-Pb zircon age of 1500 Ma for a quartz mon zonite pluton, while samples of an older gneiss yield Rb-Sr ages that scatter between 1600 - 1775 Ma. Turek and Robinson (1982) report a whole rock isochron age for basement samples from southwestern Ontario of 1560 140 Ma for 6 samples. Three other samples register ages of 1830 Ma, 915 Ma and 670 Ma. The 1560 Ma and 1830 Ma ages are probably survival ages, they fall in the 1500 - 1800 Ma age group for Ontario Gneiss Segment IIIA of Wynne-Edwards (1972). The 915 Ma age is a typical Grenvillian age while the 670 Ma is probably related to move ment along the Electric fault as the sample comes from hole #114 which is close to the Electric fault. f-t P- f! 00 M CM * * ea CM CM S

Metamorphic Grade No diagnostic mineral assemblages have been observed to pin point the grade of metamorphism. Sample //398d contains plagioclase, diopside, biotite, quartz, calcite and hornblende. Such an assemblage is character istic of impure calcareous rocks metamorphosed to granulite facies (Jackson, 1970). Sample #3 contains glauconite, indicating a maximum metamorphic grade of lower greenschist. Possibly this sample is not Precambrian but basal Cambrian, however, this glauconite bearing rock is overlain by a pegmatite. It is difficult to envisage such a low grade of metamorphism and, of course, it is possible that the pegmatite in hole 3 is a boulder lying on a Cambrian glauconitic sandstone, or somehow the sandstone is Cambrian but in a topographic trap and is found lower in the hole. The general metamorphic grade for the exposed Grenville is amphibolite facies, and It is expected that this is the general grade of metamorphism in the basement. As there are local variations in the in tensity of metamorphic grade In the exposed Grenville, local variations can be expected in the basement.

Regional Correlations

The Precambrian basement of southern Ontario is an extention of the

exposed Grenville province of the Canadian Shield. It is difficult to extrapolate the geology of the exposed shield to the buried basement be cause of a lack of drilling in the areas adjacent to the exposed shield. A body of mixed clastic and carbonate metasedimentary rocks north of

Trenton is on strike with a belt of marble exposed at the surface in Marmora township to the north. An occurrence of marble north of Markham 39 may be part of another belt of marble exposed at the surface in Galway township to the northeast. The occurrence of marble appears to be one of the key characteristics of the Central Metasedimentary Belt of Wynne Edwards (1972) shown in Pig. 14. Thus, the occurrence of marble in the southern portion of the study area, in association with clastic metasedimentary rocks indicates that the Central Metasedimentary Belt may extend further to the southwest, as far west as Sarnia and as far south as Erie au. The belt may be continuous but the large number of holes intersecting granite and syenite between intersections of metasedimentary rocks seem to indicate otherwise. The large body of clastic metasedimentary rocks near Wingham does not contain any marble, and is probably part of the Ontario Gneiss Segment of Wynne-Edwards (1972), Fig. 14. The Ontario Gneiss Segment is shown in Fig. 14 curving southwards through Lambton and Kent Counties, which are dominantly syenitic in composition (Robinson, 1980).

The Grenville Front Tectonic Zone of Wynne-Edwards (1972) can also be extended into the subsurface. While most of this zone underlies

Lake Huron it also curves southwards and underlies Essex County. This hypothesis would be consistent with the magnetic pattern for Essex

County (Fig. 12). The observed pattern here has a northwesterly trend and low magnetic intensity, this is a characteristic of the Grenville

Front Tectonic Zone (Wynne-Edwards, 1972, Van Shmus 1975, Nwachukwu (1965)

Kellog (1971) produced a geological map for the basement of Michigan

15 . Precambrian basement in Michigan^ af*ter Kellog 42 is very general and is not comparable in detail with this study.

Kellog (1971) shows a belt of Keweenawan volcanics (Fig. 15) as underlying the Detroit area. Such a belt cannot be extended into

Ontario, as basement samples for Essex county are granite, syenite, granodiorite gneisses and very minor clastic metasedimentary rocks.

Furthermore, the magnetic anomaly map (Fig. 12) of Nwachukwu (1964) shows very low magnetic relief for the Windsor area. If the area was underlain by Keweenawan basalts, a high magnetic anomaly would be expected.

ECONOMIC GEOLOGY

The topography of the Precambrian basement is important to oil and gas exploration, as the basal Cambrian rocks are known reservoir rocks, and their areal distribution and thickness is controlled by

Precambrian topography.

The economic potential of the Precambrian rocks themselves should be similar to that for the exposed Grenville province. In the exposed

Grenville there are numerous small occurrences of precious metals, mostly gold", in the metasedimentary-metvolcanic belts of the Central

Metasedimentary Belt. There are also several Pb-Zn occurrences in the marbles of the exposed Grenville, and there is good possibility that the marbles of the basement may also host Pb-Zn mineralization. Sample

//449b, a marble, contains 204 ppm Zn, which is relatively high value and may indicate mineralization in the area.

It is possible that iron formations may exist in the Precambrian 43 basement although there were no indications to suggest the presence of iron formation in the study area. The several gabbro occurrences observed show no sulphides, and the pegmatites observed are of the simple type with no uranium, lithium or rare earth minerala present. There are two interesting occurrences of mineralization that have been found in the basement. Hole #211 (chip samples) intersected at * -764.4 m what is thought to be a quartz vein with pyrite and sphalerite. Hole #538 (core) intersected granite pegmatite containing blebs of mag netite at -210.3 m to -213.3 m and -223.4 m to -224.1 m. The logs for both of these holes are given in Appendix D.

Weathering of the Precambrian has left a saprolith up to 3 m thick. It is possible that lateritic deposits may have formed in the tropical environment present during the period 950 Ma to 650 Ma. Mechanical sorting may in some places have produced placer type deposits. Basement faults may have been conduits for fluid migration, which could lead to mineralization in the overlying Paleozoic rocks. 44

Lithology Map

MARGINAL NOTES Igneous and metaigneous rocks have been classified according to

the IUGS convention (Streckeisen, 1373). The specific rock type for each hole is listed in the petrography file. For the purposes of this map the rock types have been combined into 7 units composed of the following: 1) Granite - Granite, alkali-feldspar granite, quartz rich granitoids. 2) Granodiorite and Tonalite - Granodiorite and tonalite. 3) Syenite - Syenite, alkali-feldspar quartz syenite, quartz syenite, alkali feldspar syenite, monzonite, quartz monzonite. 4) Gabbro - Gabbro, monzogabbro, diorite, anorthosite. 5) Amphibolite - Amphibole rich rock with minor feldspar, biotite, quartz. 6a) Clastic metasediments - sandstone, arkose, greywacke, siltstone, quartzite, schist. 6b) Marble - Pure to Impure with calc-silicate minerals, crystalline carbonate rock. The distribution of granite and syenite is very intermixed and perhaps should be considered together. On the other hand granodiorite, and minor tonalite, appears to occur in discrete areas and are shown as such. Gabbro and other basic rocks appear to be spatially related to the distribution of metasedimentary rocks. Areas of metasedimentary rocks appear to have a northeasterly-southwesterly trend. Compositionally they are mostly clastic rocks. Four areas of marble form mappable units 132

two of these adjoin clastic metasedimentary rocks.

The rock contacts are interpolated from drill hole intersections of the specific rock type. The magnetic anomaly map of Nwachukwu (1964) gives some support for the occurrence and distribution of medasedimentary and gabbroic rocks. Some of the.gabbros show tip as magnetic highs, while the metasedimentary rocks are associated with magnetic lows. No convincing evidence has been found to suggest the existence of. metavolcanic rocks in the area, unless the occurrence of amphibolite in four separate and isolated holes can be construed to represent volcanic rocks. The distribution of metasedimentary rocks and granitic rocks indicates the granitic rocks are more extensive. Drill hole coverage of the northeastern part of the study area is sparse. This makes it difficult to extrapolate from the Precambrian Shield to the subsurface. However, north of Trenton there is an occurrence of marble which is on strike with exposed marble on the Shield to the northeast. The two large areas of metasedimentary rocks, north of London, cannot be extrapolated northeastwards to the exposed Shield as there are intervening holes with granitic rocks. Nevertheless, these metasedimentary rocks may be an extension and .part of the Central Metasedimentary Belt TV B of Wynne- Edwards (1972). The economic potential of the Precambrian basement may be in the existence of good quality marble, possible mineralization associated with the gabbros and pegmatites, and also occurrence of iron formations with the metasedimentary rocks, though in this study, no iron formations have been identified, the pegmatites are simple and the gabbros do not 133

contain sulfides. There are, however, two occurrences of mineralization that are noteworthy. Hole #211 intersected quartz (presumably a quartz vein) with pyrite and brown sphalerite, and hole #538 intersected a pegmatite containing blebs Cup to l cm) of magnetite. The weathered top of the Precambrian surface appears to Be an in situ paleoregolith up to 3 m thick which may, in places, be mechanically sorted to produce placer type deposits.
