Summary

Articles of the volume are devoted to mineralogy, including descriptions of new mineral species (telyushenkoite – a new caesium mineral of the leifite group, neskevaaraite-Fe – a new mineral of the labuntsovite group) and new finds of minerals (pabstite from the moraine of the Dara-i-Pioz glacier, Tadjikistan, germanocolusite from Kipushi, Katanga, minerals of the hilairite group from Khibiny and Lovozero massifs). Results of study of mineral associations in gold-sulfidetellyride ore of the Kairagach deposit, Uzbekistan are presented. Features of rare germanite structure are revealed. The cavitation model is proposed for the formation of mineral microspherulas. Problems of isomorphism in the stannite family minerals and additivity of optical properties in minerals of the humite series are considered. The section Mineralogical Museums and Collections includes articles devoted to the description and history of Museum collections (article of the Kolyvan grinding factory, P.A.Kochubey's collection, new acquisitions) and the geographical location of mineral type localities is discussed in this section. The section Mineralogical Notes includes the article about photographing minerals and Reminiscences of the veteran research worker of the Fersman Mineralogical Museum, Doctor in Science M.D. Dorfman about meetings with known mineralogists and geochemists – N.A. Smoltaninov, P.P. Pilipenko, Yu.A. Bilibin.
The volume is of interest for mineralogists, geochemists, geologists, and to museum curators, collectors and amateurs of minerals.

Atali A. Agakhanov, Leonid A. Pautov, Dmitriy I. Belakovskiy, Elena V. Sokolova, Frank C. Hawthorne. Telyushenkoite CsNa₆[Be₂(Si,Al,Zn)₁₈O₃₉F₂] – a new cesium mineral of the leifite group, p. 5 - 8

A new mineral, telyushenkoite, was discovered in the Dara-i-Pioz alkaline massif (Tajikistan). It occurs as white or colorless vitreous equant anhedral grains up to 2cm wide in coarsegrained boulders of reedmergnerite associated with microcline, polylithionite, shibkovite and pectolite. The mineral has distinct cleavage, Mohs hardness = 6, VHN₁₀₀ = 714(696737) kg/mm², Dmeas. = 2.73(1), Dcalc. = 2.73g/cm³. In transmitted light, telyushenkoite is colorless and transparent. It is uniaxial positive, ω = 1.526(2), ε = 1.531(2). Singlecrystal X-ray study indicates trigonal symmetry, space group P3m1, a = 14.3770(8), c = 4.8786(3) Å, V = 873.2(1)ų , Z = 1. The strongest lines in the powderdiffraction pattern are [d(I,hkl)]: 12.47(7,010), 6.226(35,020), 4.709(21,120), 4.149(50,030), 3.456(40,130), 3.387(75,121), 3.161(100,031), 2.456 (30,231). The chemical composition (electron microprobe, BeO by colorimetry) is SiO₂ 64.32, Al₂O₃ 7.26, BeO 3.53, ZnO 1.71, Na₂O 13.53, K₂O 0.47, Cs₂O 6.76, Rb2O 6.76, F 2.84, O = F 1.20, total 99.37 wt.%, corresponding to (Cs_0.69Na_0.31K_0.14Rb_0.02)_1.16Na_6.00 [Be_2.04(Si_15.46Al_2.06Zn_0.30)_17.82O_38.84F_2.16]. Telyushenkoite, ideally CsNa₆[Be₂ (Si₁₅Al₃)₁₈ O₃₉F₂], is the Cs-dominant analogue of leifite, ideally NaNa₆[Be₂(Si₁₅Al₃)₁₈O₃₉F₂]. читать далее...

Neskevaaraite-Fe, a new labuntsovitegroup mineral, was found in the Vuoriyarvi alkaline-ultramafic pluton, Northern Karelia, within a hydrothermally altered carbonatite body. The mineral occurs as rough brown translucent prismatic crystals up to 6 mm long. Associated minerals are dolomite, calcite, phlogopite, fluorapatite, pyrite, pyrrhotite, chalcopyrite, serpentine, and nenadkevichite. Another occurrence is a fieldsparecalcite vein located in the Kukisvumchorr Mt., Khibiny, Kola Peninsula, where the new mineral is closely associated with labuntsoviteFe. читать далее...

Leonid A. Pautov. Pabstite from the Dara-i-Pioz moraine (Tadjikistan), p. 15 - 19

Pabstite was discovered in the moraine of the DaraiPioz glacier (Garmsky district, Tadjikistan) in a leucocratic rock mainly composed of microcline, quartz, and albite. Subordinated minerals are aegirine, titanite, astrophyllite, bafertisite, galena, sphalerite, ilmenite, pyrochlore, fluorite, zircon, fluorapatite, and calcite. Pabstite forms grains and wellfaced crystals (0.10.5 mm), growing on quartz crystals in small cavities abundant in the rock. Its composition is close to the final member BaSnSi3O9 in the series pabstitebenitoite. Microprobe analysis has shown: SiO₂ – 37.43; TiO₂ – 0.19; ZrO₂ – 0.16; SnO₂ – 30.05; BaO – 32.41; total 100.24. The empirical formula is Ba_1.02(Sn_0.96Ti_0.01Zr_0.01)_0.98Si_3.01O₉. Refraction parameters of pabstite are n_o = 1.668(2); n_e = 1.657(2), which is much lower than cited figures for pabstite from the type locality. Strong dependence of pabstite optical properties on titanium contents is shown. The find of pabstite at DaraiPiozе is the first find of pabstite in alkaline rocks and, apparently, the second find of this mineral in the world. читать далее...
