Terms considered obsolete are *asterisked. Rock-names specifically approved by the lUGS Subcommission on the Systematics of Igneous Rocks (Streckeisen 1976, 1979; Le Maitre 1989) are in BOLD CAPITALS. Other definitions are based on the consensus in Johannsen (1938), S!llrensen (1974), Tomkeieff (1983), Nixon (1987, p.761) and Bates & Jackson (1989). Cross-references to other entries below are in bold type. In the main text, enclosure of a cited term in "double quotes" indicates that the usage does not agree with this glossary. Absarokite. The basic member of the shoshonite association. A mildly potassic basaltic rock composed of plagioclase and clinopyroxene ± olivine and minor K-feldspar. Type locality Absaroka, Wyoming, USA. [Definition after Joplin 1968]. Accidental. Applies to xenoliths and xenocrysts of country wall rocks caught up by an intrusion. Opposite of cognate (Table 6.1). Ach'uaine hybrid suite. A suite of highly heterogeneous, olivine-hornblende-biotite-rich rocks forming irregular, pipe-like bodies satellite to Caledonian granitoid plutons in Sutherland, Scotland. Range from ultramafic rocks (e.g. scyelite) to acidic rocks, with intermediate members formed by hybridisation of the two. Associated with calc-alkaline lamprophyre dykes, and closely related to the Appinite suite. Type locality Achu'aine, Sutherland, Scotland. The name means greenfield in Gaelic, and refers to the fertility of the soil over these bodies by comparison with the brown heath over the Moine psammite country-rocks. Aillikite. See Table 1.1. Major variety of ultramafic lamprophyre consisting of combinations of forsteritic olivine, diopsidic pyroxenes, various amphiboles and phlogopite in a matrix of similar minerals with abundant primary carbonate and often minor perovskite, but little or no melilite or feldspathoids. Covers most rocks previously termed central complex kimberlite. Type locality Aillik Bay, Canada; named by Kranck {1939). * Aiounite. An obscure local name for an augite-apatite-rich variety of perhaps hyalomonchiquite. Alkaline lamprophyres. A group of lamprophyres consisting of the rock-types camptonite, rnonchiquite, sannaite, which correspond broadly to alkali basalts, basanites and nephelinites, but are considerably more enriched in volatile-elements (H20,C02, F, Cl) and to some extent in LILE elements {K, Rb, Ba, etc.) Alkaline rock. An igneous rock carrying feldspathoids and/or soda pyriboles (aegirine, arfvedsonite, etc.), implying the presence of normative ne, /c,/a and/or ac, ns, ks. [Definition after Woolley 1987]. ALNOITE. See Table 1.1. Major variety of ultramafic lampropbyre consisting of combinations of forsteritic olivine, diopsidic pyroxenes, various amphiboles and phlogopite in a matrix of similar minerals with abundant melilite and often minor perovskite, primary carbonates and/or feldspathoids. Type locality Alnl:l, Sweden; named by Von Eckermann (1948). Amygdale. Genetic term for a particular type of globular structure formed by condensation of a late-stage hydrothermal fluid into pre-existing cavities formed by gas bubbles. Anchibasaltic rock. Termed applied by Wimmenauer (1973b) to alkaline lamprophyres. Ankaratrite. A biotite-rich nephelinite, marking among the closest equivalents among volcanic rocks to ultramafic lamprophyres (Section 7.3.4). The type rock from Madagascar has 01 10, Cpx 26, Bi 8, Ne 14, II 12 (Johannsen 1938) and fits the present definition of ouacbitite; an associated melilite-ankaratrite fits the definition of alniiite. * Antsohite. An obscure local name for a lamprophyric dyke rock from Antsohy, Madagascar, consisting of phenocrysts of biotite in a groundmass of biotite, hornblende and interstitial quartz. Probably a feldspar-poor kersantite. Appinite. See Section 7.1.1. Originally defined by Bailey & Maufe in 1916 as "plutonic equivalents of the hornblende vogesites and spessartites" (see Bailey 1960), but since used to refer to a panoply of mostly unrelated hornblende-phyric minor intrusions, ranging from gabbro to monzogabbro, diorite, syenite and even granodiorite. Appinitic has generally been used to imply the presence of coarse euhedral homblendes and an association with more basic appinites. Restricted

  • Summary of the Mineral Information Package for the Khanneshin Carbonatite Area of Interest
    Chapter 21A. Summary of the Mineral Information Package for the Khanneshin Carbonatite Area of Interest Contribution by Robert D. Tucker, Harvey E. Belkin, Klaus J. Schulz, Stephen G. Peters, and Kim P. Buttleman Abstract The Khanneshin carbonatite is a deeply dissected igneous complex of Quaternary age that rises approximately 700 meters above the flat-lying Neogene sediments of the Registan Desert, Helmand Province, Afghanistan. The complex consists almost exclusively of carbonate-rich intrusive and extrusive igneous rocks, crudely circular in outline, with only three small hypabyssal plugs of leucite phonolite and leucitite outcropping in the southeastern part of the complex. The complex is broadly divisible into a central intrusive vent (or massif), approximately 4 kilometers in diameter, consisting of coarse-grained sövite and brecciated and agglomeratic barite-ankerite alvikite; a thin marginal zone (less than 1 kilometer wide) of outwardly dipping (5°–45°). Neogene sedimentary strata; and a peripheral apron of volcanic and volcaniclastic strata extending another 3–5 kilometers away from the central intrusive massif. Small satellitic intrusions of biotite-calcite carbonatite, no larger than 400 meters in diameter, crop out on the southern and southeastern margin of the central intrusive massif. In the 1970s several teams of Soviet geologists identified prospective areas of interest for uranium, phosphorus, and light rare earth element (LREE) mineralization in four regions of the carbonatite complex. High uranium concentrations are reported in two regions; the greatest concentrations are confined to silicified shear zones in sandy clay approximately 1.1 kilometers southwest of the peripheral part of the central vent. An area of phosphorus enrichment, primarily occurring in apatite, is present in coarse-grained agglomeratic alvikite, with abundant fenite xenoliths, approximately 750 meters south of the periphery of the central vent.

  • Mineralogy, Geochemistry and Petrology of a Pyrochlore-Bearing Carbonatite at Seabrook Lake, Ontario
    Mineralogy, Geochemistry and Petrology of a Pyrochlore-bearing Carbonatite at Seabrook Lake, Ontario by Myron John Osateriko B.Sc, University of British Columbia, 1965 A Thesis Submitted in Partial Fulfilment ' of the Requirements for the Degree of MASTER OF SCIENCE in the Department of GEOLOGY We accept this thesis as conforming to the required standard THE UNIVERSITY OF BRITISH COLUMBIA April, 1967 In presenting this thesis in partial fulfilment of the requirements for an advanced degree at the University of British Columbia, I agree that th3 Library shall make it freely available for reference and study. I further agree that permission for extensive copying of this thesis for scholarly purposes may be granted by the Head of my Department or by his representatives. It is understood that copying or publication of this thesis for financial gain shall not be allowed without my written permission. Depa rtment The University of British Columbia Vancouver 8, Canada i ABSTRACT The Seabrook Lake carbonatite complex is one of the smallest of nine known carbonatite complexes in central Ontario. The complex, which is one-half square mile in area and pear- shaped in plan, consists of fenitized granite and breccia, mafic breccia, ijolite and related breccia, and carbonatite. The bulbous northern part of the complex consists of a plug-like core of carbonatite surrounded by mafic breccia and carbonatite dykes. The narrow southern part consists of ijolite and related breccia. Enveloping all of these rocks.is a fenitized aureole which grades outward to unaltered granite that underlies much of the surrounding area. The carbonatite is composed of calcite with the following minor mineral, in decreasing order of abundance: goethite, microcline, magnesioriebeckite-riebeckite, magnetite-ulvospinel, apatite, hematite, pyrite, albite, biotite, chlorite, pyrochlore, brookite, sphene, ferroan dolomite (ankerite?), aegirine, chalcopyrite, wollastonite and quartz.

  • Geology of the Cluggerfluorite Deposit
    Revista Brasileira de Geociências 17(3): 288-294, setembro de 1987 GEOLOGY OF THE CLUGGE RFLUORITE DEPOSIT. MATO PRETO. PARANÁ. BRAZIL ROBERT E. JENK INS n- ABSTRACT The Mato Preto fluorite deposite are located in the Ribeira River valley 80 km NNE from Curitiba, Paraná, Brazil. They consist of three known orebodies and numerous minar occurrences wi­ thin an area of about 15 km ê. Clugger, the largest dcposit, is a hydrothermnl replacemcnt and fracture-fil­ ling type in a brecciated and sheared contact zone among carbonatitc, nephellne syenitc, phonolite, and tin­ guaite of the Cretaceous-Paleocene age Mato Preto Igneous Complex. Fluorite occurs LS four subparallel but coalescing ore lenses which forro envelopes about dikes of phonolite-tinguaite and have strlke lengths of 250 m, aggregate thickness up to 80 m, and extend to at least 120 m in depth . Dikes and Ienses strike N50-55E and dip steeply to the northwest. Fluorite forms matrix replacemcnts and crosscutting veins in premineral and intermineral breccias adjacent to dikes. Fluorite mineralizatioo has been introduced in at least two pulses and is associated with barite-celestlre, apatite, rare earth minerais, and sulfides. Late explosive venting of the system has formed pipes of volcanic breccia with crackle breccia in ore adjacent. Fluorite along breakage planes is recrystallized into monomineralic veinlets. Mineralization is associated with fracture controlled epidote aJteration, but major silicification apparently predates ore. The c1ugger deposit was probably fonne d at low pressures and temperatures, possibly within a vent of a now-eroded Mato Preto volcano. RESUMO Os depósitos de Iluorita de Mato Preto situam-se no vale do Rio Ribeira, 80 km a NNE de Curitiba,Paraná.

Signature of Author: 16th January 2018 Abstract Evidence exists for great volumes of water on early Mars. Liquid surface water requires a much denser atmosphere than modern Mars possesses, probably predominantly composed of CO2. Such significant volumes of CO2 and water in the presence of basalt should have produced vast concentrations of carbonate minerals, yet little carbonate has been discovered thus far.

Morphological and mineralogical associations, and compositional analysis of the Sr-rich apatite, were carried out using an electron microprobe. Two principal types of apatite were distinguished. One type occurs as short-prismatic crystals with Sr-rich rims, while another type with acicular or finely columnar shapes constitutes Sr-rich apatite element maps and systematic quantitative analysis of apatite revealed great variations in SrO content (0.42%–26.79%). The calculated structural formula of the measured Sr-rich apatite is: (Ca3.15–4.963Sr0.019–1.510Ba0.00–0.030Na0.006–0.108REE0.106–0.153) (P2.84–3.028Si0.009–0.094)O12(F0.675–1.079, Cl0.000–0.256, OH0.084–0.297). Mineralogical textures of apatite implied a replacement mechanism for the Sr-rich apatite.

Orickite,Na,KrCuse5Fer.ooSz.zHzO (x,y < 0.03,z < 0.5),is hexagonal;a:3.695, c : 6.164 (both t0.0lA); D = 4.212g cm-3 forZ:4. The six strongestlines in the X-ray diffraction powder pattern are [d in A, t, (*ttt):3.08, 100,(002); 3.20 90, (100);2.84,60, (l0l); 1.73,55, (103);1.583,30, (ll2);2.20, 15,(102). The mineralis brassyellow and opaque, weakly pleochroic, but strongly anisotropic (from grayish brown to grayish blue) in reflected light. Orickite is compositionally near iron-rich chalcopyrite, but the mineral may be related to synthetic chalcogenideshaving a distorted wurtzite-\2[I) structure. Coyoteite, NaFe3S5.2H2O,is triclinic, Pl or Pl; a : 7.409(8),b : 9.881(6),c = 6.441(3)A,a:100'25(3)',F=104"37(5)',y=81"29(5)':D=2.879ecm-3forZ=2.Thesix strongestlines in the powder patter! are: 5.12,100,(lll);7.13,90,(100);3.028,80,(220); 3.08O,70,(OO2);9.6,60,(010);5.60,60,(01l). Coyoteite is black and opaque;in reflectedlight it is pale brownish gray, faintly pleochroic, and strongly anisotropic (from gray to dull golden orange).
