Pdf icon.pngAgakhanov A.A., Pautov L.A., Uvarova Y.A., Sokolova E., Hawthorne, Frank C., Karpenko V.Y. Nalivkinite Li2NaFe2+7Ti2(Si8O24)O2(OH)4F, a New Mineral of the Astrophyllite Group from the Darai-Pioz Massif, Tadjikistan, p. 5 - 12

Nalivkinite, a new astrophyllite-group mineral, was discovered in the moraine of the Darai-Pioz alkaline massif located at the intersection of the Zeravshansky, Turkestansky and Alaisky Ridges, Tadjikistan. Nalivkinite occurs in the amphibole-quartz-feldspar rock in association with calcybeborosilite-(Y), bafertisite, jinshajiangite, zircon and thorite. Nalivkinite is brown with a bronze hue and a vitreous luster; in thin plates, it is transparent. Mohs hardness is 3, Dmeas. = 3.32(2) g/cm3, Dcalc. = 3.315 g/cm3. It is biaxial positive, np = 1.703(2), nm = 1.716(2), ng = 1.745(2), 2Vmeas. = +68(2)°, 2Vcalc. = +68.6°. Nalivkinite is triclinic, space group P1, a = 5.3745(6) Å; b = 11.9299(15) Å; c = 11.6509(14) Å; a =113.325(3)°, b = 94.524(2)°, g = 103.080(2)°, V = 656.2(2) Å3, Z = 1. Cell dimensions refined from X-ray powder diffraction data are as follows: a = 5.3707(2) Å; b = 11.9327(5) Å; c = 11.6546(4) Å; a =113.384(1)°, b = 94.547(1)°, 103.047(1)°, V = 655.85(2) Å3. The strongest reflections in the X-ray powder diffraction powder pattern are as follows: [(d, Å), (I, %), (hkl)]: 10.56 (100) (001), 3.50 (100) (003), 2.780 (80) (1–42), 2.648 (45) (211), 2578 (70)(130), 2.474 (15) (212), 2.295 (30) (131), 2.106 (35) (142), 1.760 (30) (133), 1.660 (15) (0–73). The infrared spectrum of nalivkinite is similar to that of astrophyllite, and the strongest lines are as follows (cm–1): 3600, 1621, 1077(sh), 1056, 975, 929, 696, 649, 566, 441, 438. The chemical composition (electron microprobe, wt. %, Li2O and Rb2O by ICP OES, H2O by the Penfield method): Al2O3 – 0.67, SiO2 – 35.92, TiO2 – 10.50, Nb2O5 – 1.68, CaO – 1.29, MgO – 0.09, MnO – 5.26, FeO – 32.76, Na2O – 1.62, K2O – 2.49, Li2O – 3.76, Cs2O – 1.40, Rb2O – 0.85, H2O – 3.13, F – 0.75, -O=F2 – 0.32, total – 100.04. The empirical formula of nalivkinite is (Li1.03K0.69Cs0.13Rb0.12)1.97(Na0.69Ca0.30)0.99(Fe2+5.97Mn0.97Mg0.03)6.97(Ti1.72Nb0.16Zr0.08)1.96[Si7.83Al0.17]8O25.98OH4.07 (F0.52OH0.48)1.00 and the ideal formula is Li2NaFe2+7Ti2(Si8O24)O2(OH)4F. The crystal structure of nalivkinite was refined to an R1 index of 6.26%. The name honors Dmitry Vasiljevich Nalivkin, a famous Russian geologist (1889–1982), author of numerous works on the geology, stratigraphy and paleontology of Central Asia. The holotype sample of nalivkinite is deposited at the Fersman Mineralоgical Museum, Russian Academy of Sciences, Moscow. читать далее...

New data on a number of rare minerals of In, Cd, Mo, and W, which have been obtained using modern analytical techniques, are described in this article. These minerals have been identified in gold-rich polymetallic ore superimposed on Mo(W) stockwork porphyry mineralization. Indium mineralization presents extremely rare dzhalindite In(OH)3 that was previously described in Russia only from deposits Dzhalinda, Amur region and Verkhnee, Primorsky krai as supergene mineral. Tungsten and molybdenum are concentrated in rare intermediate phase of the wulfenite-stolzite series Pb(W0.74Mo0.26)O4, and Cd, in greenockite CdS. Occurrence of well-shaped cubic crystals of dzhalindite exclusively in quartz and association of the mineral with sphalerite, native silver, and electrum allow suggesting its hypogene origin (in contrast to previous findings as supergene pseudomorphs after indium sulfide). However, additional investigation is required to establish formation conditions of dzhalindite. читать далее...

New data on black powellite from a Mo-U deposit, South Kazakhstan are given. Bipyramidal crystals of the mineral have been found in intimate association with uranium minerals of the oxidized zone, including uranyl-arsenate mica (uramarsite) and uranyl silicate uranophane-beta. X-ray diffraction, infrared spectroscopy, differential thermal analysis (DTA), analytical scanning electron microscopy (ASEM), electron microprobe, X-ray fluorescence analysis (XRFA), and laser spectrography have been performed to examine the mineral. Two varieties of powellite have been identified: crystalline in uranophane and amorphous in uranate. The causes of black color of powellite are discussed. This coloration of powellite can be prospecting guide for deposits of radioactive elements. читать далее...

Pdf icon.pngPovarennykh M.Yu. Typomorphism of the Columbite-Tantalite Group Minerals in the Rare-Metal Tantalum-bearing Amazonite-Albite Granites, p. 37 - 44

Mineralogical investigation of three tantalum-bearing granite massifs Orlovskoe and Aetykinskoe (Transbaikalia) and Maykul`skoe (Kazakhstan) has been conducted. Typomorphic peculiar features of the columbite–tantalite (Col-Ta) group minerals in these massifs according to their connection with different age phase and facial granite varieties have been revealed. It has been shown that combined with the other typomorphic signs crystal morphology peculiar features of the Col-Ta group minerals could be advantageously used during the geological prospecting for the survey and estimation of tantalum ore occurrences within the massifs of amazonite–albite rare metal subalkalic type granites. Col-Ta typomorphic signs may be also used at the stage of the detailed and exploitation exploration during the mineralogical and technological mapping of tantalum deposits in such massifs. читать далее...



Pdf icon.pngChernikov A.A., Dubinchuk V.T., Tolkachev A.E., Chistyakova N.I., and Nechelyustov G.N. Mineralogical and Geochemical Features of Deposits in the Southeastern Transbaikalia for Local Forecast of Uranium Ore, p. 45 - 52

A.A. Chernikov discovered the uranium-molybdenum hydrochemical anomaly in the southern Argun region (southeastern Transbaikalia) that had been forcible argument for geological substantiation to renew research and exploration for uranium in this region. This anomaly is important to understand a state of supergene zone of uranium deposits with leached near-surface oxidired zone in the region. The Strel’tsovsk-Antei largest uranium deposits in Russia (Laverov et al., 1991, 1992) are characterized by great vertical extension (2.7 km) of ore mineralization and variation of ore mineralogy, mineralogy of metasomatic and host rocks downward (Ishchukova and Modnikov, 1991; Andreeva et al., 1996; Chernikov, 2006/2007). Chernyshov and Golobev (1996) reported and we confirmed in this study that massive pitchblende ore was deposited within interval 134–136 (~150) Ma. Isotopic age of “protore” is 250–260 (~300) Ma; age of Th-bearing uraninite is ~500 Ma and older. New data indicated that uranium (IV) oxides and silicates, including coffinite, uranium titanates, and brannerite, in ore of the Antei deposit are young, from zero to few Ma. Exclusively very young uranium (IV) silicates and titanates are observed at lower levels of the Anntei deposit. These mineral precipitated from meteoric water infiltrated from surface into deep levels of the deposit. The basic level of karst and fracture rocks can be probable outflow area of meteoric water at the Argun deposit. Distribution of oxygen and carbon isotopes in the Argun and Antei structural clusters confirms the main role of meteoric solution to form various minerals at the uranium deposits; this is important for revealing additional exploration and estimation criteria for these deposits. Large uranium accumulations are predicted to the northward of the Strel’tsovsk structure. читать далее...

Pdf icon.pngYamnova N.A., Egorov-Tismenko, Yu.K., Gobechiya E.R., Zadov A.E., Gazeev V.M. New Data on Polymorphs of Anhydrous Dicalcium Orthosilicate, p. 54 - 71

This article describes new data on polymorphous modifications (a, a’L, a’H, b, g) of Ca2SiO4. Structural features and mechanisms of phase transition between Ca2SiO4 polymorphs interrelated to modifications of K-Na sulfate aphthitalite (glaserite) K3Na[SO4]2 have been analyzed with regard to modular theory and theory of the closest packing. The major structural module [12]M(1)[6]M(1’)[10]M(2)2[TO4]2 (M = K, Na, Ca, Mg; T = S, Si) has been revealed for the Ca2SiO4 modifications and relative natural “glaserite-type” silicate minerals, bredigite Ca7Mg[SiO4]4 and merwinite Ca3Mg[SiO4]2; and calcio-olivine (γ-Ca2SiO4) examined by the authors. The structural glaserite modules similar in symmetry and composition in the structures of described compounds account for topotactic character and reversible phase transition between the Ca2SiO4 polymorphs on the one hand and abundant assemblages of the mineral series on the other. читать далее...



Pdf icon.pngChukanov N.V., Rozenberg K.A., Rastsvetaeva R.K., Möckel Steffen New Data on Titanium-rich Biotite: a Problem of “Wodanite”, p. 72 - 77

Titanium-rich mica of the biotite series (“wodanite”) was found in tefrite of paleovolcano Rothenberg, Eifel, Germany, and studied by combining of electron microprobe analysis, IR spectroscopy and single-crystal structure analysis. The mineral is monoclinic, space group C2/m; unit-cell parameters are: a = 5.3165(1), b = 9.2000(2), c = 10.0602(2) Å, b = 100.354(2) . The presence of Ti results in strong distortion of the octahedron M(2). IR spectrum demonstrates the absence of detectable amounts of OH groups. The empirical formula of Ti-rich biotite is: (K0.74Na0.15Ca0.05)S0.94(Mg1.60Ti0.74Fe2+0.62Cr0.04)S3.00[(Si2.61Al1.29Fe3+0.10)S4.00O10](O1.17F0.71). Regularities of isomorphous substitutions, as well as genesis of Ti-rich micas of the biotite series are discussed. The idealized formula of the magnesium-titanium end member of this series is: K(Mg2Ti)(Si3AlO10)O2. читать далее...

Mineralogical Notes

Pdf icon.pngSpiridonov E.M. Fe-dominant Bogdanovite from Cementation Zone of the Aginsky Gold-Telluride Deposit, Kamchatka Peninsula, Russia, p. 143 - 145

Fe-dominated bogdanovite, Au5CuFe2(Te,Pb)2, a specific supergene mineral, occurs in the weathering profile (in cementation zone) of the Aginsky gold-telluride deposit, Kamchatka Peninsula, Russia. Bogdanovite has been formed as a result of replacement of hypogene kostovite, krennerite, sylvanite, altaite, nagyagite, bornite, and chalcopyrite. The mineral is associated with Fe-Pb and Fe-Cu-Pb tellurites. In the oxidized zone, bogdanovite is replaced by finegrained segregations of gold, balyakinite, and plumbotellurite. The composition of Fe-dominated bogdanovite (average of four point analyses) is as follows, wt %: 60.35 Au, 2.19 Ag, 4.63 Cu, 9.33 Fe, 9.99 Te, 12.83 Pb, 0.07 Se; total is 99.39. Formula is as follows: Au4.33Ag0.29Cu1.03Fe2.36Te1.11Pb0.87Se0.01. Bogdanovite has a metallic type of conductivity and relatively high microhardness VHN20 = 290–354 kg/mm2, average 321 kg/mm2 (n = 14). The mineral is anisotropic, biaxial. It is extremely specific in reflected light. Color bireflectance varying from grey and light violet to bright golden and red, and strong color anisotropy are characteristic features. Reflectance ranges from 2 to 43% in visible light. Change of reflectance sign at 670 nm is typical. According to optical parameters, the symmetry of bogdanovite is not higher than orthorhombic. According to X-ray diffraction data, bogdanovite is interstitial superstructure of the Me4X type derived from face-centered lattice of gold. Parameter of the primitive pseudocubic subcell is 4.087 Å. Color images of Fe-dominated bogdanovite are first shown that will assist for corrected application of term bogdanovite. читать далее...

Discussions

Pdf icon.pngBorutzky B.Ye. The Essays on Fundamental and Genetic Mineralogy: 3. Minerals of Variable Composition with Variable Structure and Problems of Species Formation in Mineralogy. Eudialyte-Eucolites, p. 148 - 173

This paper is one of a series on genetic and fundamental mineralogy (Borutzky, 2005; 2006) where the problem of mineral species definition are discussed. In particular, the correlation of such fundamental terms in mineralogy as mineral – mineral species – mineral variety are considered, and compared to analogous nomenclature units in biology – another natural science. Also, the necessity for a genetic basis in mineral species definition is shown and the natural genetic taxonomy elaborated and applied to the feldspar group is demonstrated; this approach was used for the corresponding part in “Minerals” reference book (2003). The author insists that formalised structural and chemical criteria for mineral species recommended by the International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) without consideration of genesis discredits mineralogical science, because the result in unwarranted “reproduction” of abstract species which do not correspond to real discrete mineral entities widespread in certain geological environments. The paper is devoted to the detailed consideration of so-called minerals of variable composition and variable structure defined by the author (Borutzky, 1997; 1999) using the example of eudialyte-eucolites, and also the scientific and opportunistic problems accompanying the study of these chemically and structurally unique minerals. читать далее...
