Volume 45. 2010. 168 pages, 99 images, drawings, schemes. Editor: Prof. Margarita I. Novgorodova. Publication of the Institution of Russian Academy of Sciences, Fersman Mineralogical Museum RAS. This volume contains papers on the newly discovered mineral species – aleksandrovite, the Sn-analogue of baratovite, and åskagenite-(Nd), a new mineral of epidote supergroup. Discoveries of the rare minerals – irarsite (from ores of the Shanuch deposit in Kamchatka), orickite, jaipurite, westerveldite, edgarite, tung- stenite and other chalcogenides (from the Khibiny massif in Kola peninsula) are described. New data on accessory minerals from the Semeninskaya pit in the Aduy pegmatite field in the Ural Mts., on arsenosul- vanite and other sulphides from the Lebedinoe deposit in the Aldan Mts., on the composition and features of native gold from an ore occurrence in South-Eastern Kamchatka, are given. Zoned crystals of monazite- (Ce) from granite pegmatites of the Ilmeny Mts. are studied, including radiology dating. Problems of mi - neralogy and geochemistry of tetravalent uranium, uranium ores and sulfide-oxide associations in modern submarine pyrites, are covered. In the chapter “Mineral museums and collections” there is a paper on the exhibition in the Fersman Mineralogical Museum RAS dedicated to the 125th anniversary of Alexander N. Labuntsov – the discoverer of apatite deposits in the Khibiny Mts. The next chapter – “Personalities” – for the first time brings forward letters found in the RAS archives from Alexander N. Labuntsov to academician Vladimir I. Vernadsky. The “Mineralogical notes” chapter includes description of rare intergrowth twins of magnetite from the Kurzhunkul deposit, Kazakhstan, and discussion of previous mistakes in the calculation of the chemical com- position of some minerals. The “Discussions” is represented by the paper on the problems of the definition of a valid mineral species and metastable mineralization. The journal is of interest to mineralogists, geochemists, geologists and also researchers of Natural History museums, collectors and amateurs. Editor in Chief Margarita I.

Vol. 45 5 1 ALEKSANDROVITE , KLi3Ca7Sn2[Si6O18]2F2 – A NEW TIN MINERAL Leonid A. Pautov, Atali A. Agakhanov, Vladimir Y. Karpenko IRAS Fersman Mineralogical Museum, RAS, Moscow, [email protected], [email protected] Farhod G. Gafurov Tajik State university, Dushanbe, [email protected] Aleksandrovite, KLi3Ca7Sn2[Si6O18]2F2 is a new mineral, the tin analogue of baratovite. It was discovered in a moraine boulder of microcline-calcite rock, along with quartz, albite, aegirine-hedenbergite pyroxene, in the Darai-Pioz glacier (Tajikistan). The mineral association is represented by baratovite, fluorite, miserite, Sn-bearing titanite, bazirite, pabstite, Sn-bearing sogdianite, sugilite, turkestanite, fluorapatite (apatite- (CaF)). The new mineral occurs in two types: a) minute (up to 50–70 μm) lamellar grains with no zoning vis- ible under BSE, and b) crystals (up to 0.8 mm) and aggregates of zoned and sectorial grains with separate zones of aleksandrovite, and baratovite or katayamalite. The mineral is colourless, transparent, with vitre- ous lustre and pearl lustre on cleaved surface. Streak colour is white. Cleavage is perfect along (001). Density (measured) = 3.05(2) g/cm3, density (calculated) = 3.07(2) g/cm3. Microhardness is 300 kg/mm2. Mohs hardness is 4–4.5. It fluoresces light-blue under short wave UV (254 nm). The mineral is biaxial, opti- cally negative: np = 1.629(2), nm = 1.635(4), ng = 1.638(2) (589 nm); 2V (calculated) = –70.3°. Dispersion is strong, r > v. Elongation is positive, angle of extinction varies from 0° to 22°. Aleksandrovite is mono- clinic, C2/c, a = 17.01(2), b = 9.751(6), c = 21.00(2) Å, b = 112.45(8)° , V = 3219(7) Å3 , Z = 4. The strongest X-Ray lines are as follows: (d in Å (I) (hkl)): 4.86(21)(31–1); 3.712(33)(312); 3.234(100)(006); 3.206(34)(223); 3.039(28)(025); 2.894(42)(314); 2.425(42)(008); 1.950(25)(426). Chemical analysis (EMPA, an average out of 17 analyses; Li2O – ICP OES, H2O – calculated; wt.%): SiO2 – 48.01, Al2O3 – 0.07, TiO2 – 2.86, SnO2 – 12.84, ZrO2 – 1.27, Nb2O5 – 0.11, Fe2O3 – 0.27, Ce2O3 – 0.04, MgO – 0.05, CaO – 25.52, SrO – 0.39, Na2O – 0.20, K2O – 2.91, Li2O – 3.01, F – 1.71, H2O – 0.39, (O=F2) = 0.72, total 99.12. Empiric for- mula of aleksandrovite – (K0.93Na0.10)1.03Li3.02(Ca6.82Sr0.06Mn0.04Mg0.02)6.94(Sn1.28Ti0.54 Zr0.15Fe0.05Nb0.01)2.03 (Si11.98Al0.02)12O36.00[F1.35(OH)0.65]2.00. IR spectrum of aleksandrovite is similar to that of baratovite, the strongest absorption strips are: 1083, 1024, -1 974, 950, 673, 607, 568, 520, 470, 440 cm . Compatibility index is 1 – (Kp/Kc) = –0.005. The mineral is named to honour of the well-known Russian geochemist, geologist and mineralogist Stanislav Mikhailovich Aleksandrov (born in 1932) for his great contribution in geology, geochemistry and mineralogy of tin. The type specimen is stored in the Fersman Mineralogical Museum RAS in Moscow (registration number 3825/1). 5 tables, 6 figures, 19 references. Keywords: aleksandrovite, baratovite, katayamalite, Darai-Pioz, tin minerals, alkaline rocks.

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.

    U.S. DEPARTMENT OF THE INTERIOR U.S.GEOLOGICAL SURVEY ALK.BIB A selected bibliography of alkaline igneous rocks and related mineral deposits, with an emphasis on western North America compiled by Felix E. Mutschler, D. Chad Johnson, and Thomas C. Mooney Open-File Report 94-624 1994 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. INTRODUCTION This bibliography contains 3,406 references on alkaline igneous rocks and related mineral deposits compiled in conjunction with ongoing studies of alkaline igneous rocks, metallogeny, and tectonics in western North America. Much of the literature on these topics is not readily recovered by searches of current bibliographies and computerized reference systems. We hope that by making this bibliography available, it will help other workers to access this occasionally hard to find literature. The bibliography is available in two formats: (1) paper hardcopy and (2) Apple Macintosh computer-readable 3.5 inch double density diskette. The computer-readable version of the bibliography is a 725 KB WORD (version 5.0) document. Individual literature citations are arranged alphabetically by author(s) and the order of items in each citation follows the standard U.S. Geological Survey format.

  • IMA–CNMNC Approved Mineral Symbols
    Mineralogical Magazine (2021), 85, 291–320 doi:10.1180/mgm.2021.43 Article IMA–CNMNC approved mineral symbols Laurence N. Warr* Institute of Geography and Geology, University of Greifswald, 17487 Greifswald, Germany Abstract Several text symbol lists for common rock-forming minerals have been published over the last 40 years, but no internationally agreed standard has yet been established. This contribution presents the first International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) approved collection of 5744 mineral name abbreviations by combining four methods of nomenclature based on the Kretz symbol approach. The collection incorporates 991 previously defined abbreviations for mineral groups and species and presents a further 4753 new symbols that cover all currently listed IMA minerals. Adopting IMA– CNMNC approved symbols is considered a necessary step in standardising abbreviations by employing a system compatible with that used for symbolising the chemical elements. Keywords: nomenclature, mineral names, symbols, abbreviations, groups, species, elements, IMA, CNMNC (Received 28 November 2020; accepted 14 May 2021; Accepted Manuscript published online: 18 May 2021; Associate Editor: Anthony R Kampf) Introduction used collection proposed by Whitney and Evans (2010).

Dept. Mineral Sciences, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560 2 U.S. Geological Survey, MS 959, 12201 Sunrise Valley, Reston, VA 22092 1988 The Ford-Fleischer File of Mineralogical References 1982-1987 Inclusive In 1916, Prof. W.E. Ford of Yale University, having just published the Third Appendix to Dana's System of Mineralogy, 6th Edition, began to plan for the 7th Edition. He decided to create a file with a separate folder for each mineral (or for each mineral group) into which he would place a citation to any paper that contained data that should be considered in the revision of the 6th Edition. The file was maintained in duplicate with one copy going to Harvard University. In the early 1930's Palache, Berman, and Frondel at Harvard were designated chief revisionists. Assistants for the project included C.W. Wolfe and M.A. Peacock who were to gather crystallographic data at Harvard; and their counterpart, Michael Fleischer, who was to collect and evaluate chemical data at Yale. After Prof. Ford's death in March 1939, one set of his files came to the U.S. Geological Survey, and the literature has been covered since then by Michael Fleischer. Copies of the literature survey are maintained at the U.S.

Sodium releasedfrom albite: (1) combined with Ti and Fe to form myriads of acrnite cystals, many of which are strongly zoned with cores unusually rich in titanium; (2) com- bined with Ti, Fe, Mg, and Ca to form alkali amphiboles,which are zoned from fluor- richterite cores to unusual titanian-arfvedsoniterims; and (3) formed a late-stagezeolite similar to natrolite. The sequenceof ferromagnesianphases is interpreted to have been controlled partly by falling temperature,but dominately by falling /o, as the oxidized sedi- mentaryassemblage equilibrated with the reducedultramafic melt.

  • A Selective Lamprophyre Bibliography
    A Selective Lamprophyre Bibliography Compilation This Bibliography includes most publications which: (a) contain the word lamprophyre (or one of the varieties named in Fig. 1.2 and Appendix B) either in the title or as a keyword; (b) devote significant attention to lamprophyres in terms of field, petrographical or petrological description; (c) contain analytical data on lamprophyres. Those in which lamprophyres are only very briefly mentioned, and sources prior to and including those compiled by Washington (1917), are not generally included unless giving information which is critical or otherwise unavailable. References to kimberlites are not exhaustively compiled - readers should refer for example to R.H.Mitchell (1986) or to the 7 International Kimberlite Conference (IKC) volumes. Abstracts and unpublished works are excluded, unless there is no other published information on the topic. This Bibliography has been compiled over a period of over 16 years by an exhaustive combination of traditional literature search (aided by Bibliography and Index of Geology, Bulletin Signa/etique, Dissertation Abstracts International and Mineralogical Abstracts), plus usage of the many computerized geological source and reference databases now available (specifically AESIS, GEOARCHIVES, GEOBASE, GEOREF and IGBA). Note that searches from these systems on the free-text strings "minette" and "spessartite" will also raise references to sedimentary rocks and to garnets (e.g. Siehl & Thein 1978). Available compilations dealing with alkaline rocks (e.g. Heinrich 1966; Tuttle & Gittins 1966; S(6rensen 1974; Fitton & Upton 1987; Woolley 1987; Bell 1989; Mem.Geol.SocJndial5) and the 7 IKC volumes have also been searched. The rate of acquisition has now slowed to the point where the Bibliography probably includes the vast majority of relevant references; coverage of Russian and Chinese publications is probably weakest.
