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)Å3 , 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 (Cs0.69Na0.31K0.14Rb0.02)1.16Na6.00 [Be2.04(Si15.46Al2.06Zn0.30)17.82O38.84F2.16]. Telyushenkoite, ideally CsNa6[Be2 (Si15Al3)18 O39F2], is the Cs-dominant analogue of leifite, ideally NaNa6[Be2(Si15Al3)18O39F2]. читать далее...

NeskevaaraiteFe, – Fe, NaK3Fe(Ti,Nb)4(Si4O12)2(O,OH)4.6H2O – a new labuntsovite group mineral, p. 9 - 14
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...

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 Ba1.02(Sn0.96Ti0.01Zr0.01)0.98Si3.01O9. Refraction parameters of pabstite are no = 1.668(2); ne = 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...

Raremetal «zeolites» of the hilairite group, p. 20 - 33
The hilairite group includes hilairite, calciohilairite, komkovite, sazykinaite-(Y) and pyatenkoite-(Y). Their unique structural type is based on a mixed framework of screwed chains (Si3O9) and isolated Moctahedra (M = Zr, Ti, Y+Ln); large cations (Na, Ca, Ba, and subordinated K, Sr) and water molecules settle down in extensive zeolitelike cages and channels. Some features of chemical composition and properties of hi - lairitegroup minerals are easily explained if to consider them as specific raremetal «zeolites». Hilairitegro up minerals occur in hydrothermalites of the KhibinyLovozero alkaline complex, Kola Peninsula. This paper gives a review of publications on the hilairite group, describes new finds in Khibiny and Lovozero massifs, gives 29 chemical analyses of these minerals, including 17 analyses made by the authors. The isomorphous series hilairite – calciohilairite was established in material from Lovozero, as well as BaK and Srcontaining varieties of calciohilairite. The first finds of hilairite and pyatenkoite(Y) in Khibiny are described. The comparative analysis of IR spectra of all group members is given for the first time. Crystal chemistry, properties and genesis of hilairitelike minerals are discussed in view of their zeolite-like structure. читать далее...

On the Chemical Composition of Germanite, p. 34 - 40
Germanite is a very rare mineral that commonly occurs as small segregations in association with bornite, renierite, fahlores, sphalerite, galena, and other sulfides and sulfosalts. Very fine structures of replacement of germanite for renierite are often observed. Such small segregations are difficult to study. Optical properties of germanite are slightly variable in different areas and in samples from different deposits. The chemical composition (concentrations of the principal elements) of germanite varies over a wide range. In addition, the mineral was revealed to contain a wide set of admixtures. Therefore, different researchers propose different formulas for germanite. Chemical and electron microprobe analyses of germanite, accessible in literature, were compiled by the author, and peculiarities of the chemical composition of germanite were studied. It has been revealed that 28 analyses from 37 ones are adequately recalculated to the formula with 66 atoms in the unit cell; 6 analyses, to the formula with 64 atoms; and 3 analyses, with 68 atoms. The Me/S ratio in the analyses varies from 32:32 to 34:32 and to 36:32; that is, this ratio in the real analyses is inconstant. This fact suggests that we deal either with solid solutions or with three different, but similar in the chemical composition and properties, minerals. The second assumption is more probable. It is concluded that there exist three mineral species close to germanite in the chemical composition. читать далее...

On Germanocolusite from Kipushi (Katanga), p. 41 - 44
Bornite from the Kipushi ore deposit was studied in Sample 64332 from the collection of the Fersman Mineralogical Museum. It was revealed to contain small oval inclusions of germanocolusite associated with renierite, tennantite, chalcopyrite, and sphalerite. Germanocolusite from Kipushi contains slightly more Zn and V and less As, as compared to germanocolusite from the type locality. A new crystallochemical formula proposed for germanocolusite takes into account the isomorphism Zn2+ + Ge4+ → As5+ + Cu+, characteristic for complex sulfides of Ge. This is the first find of germanocolusite at the Kipushi deposit. читать далее...

Mineralogy of Epithermal Gold-Sulfide-Telluride Ores of the Kairagach Gold Deposit, (Uzbekistan), p. 45 - 56
The Kairagach ore deposit is situated on the northern slope of the Kurama Ridge (East Uzbekistan), 3.5 km
northeast of the wellknown Kochbulak goldtelluride ore deposit. According to specific mineralogical features
of the ores and hydrothermal alterations, it was assigned to the highsulfidation (or acidsulfate) type of
epithermal mineralization. However, in contrast to typical gold deposits of this type with a pronounced Au-Cu
specialization, the ores of the Kairagach deposit are characterized by the Au-Sn-Bi-Se-Te geochemical profile.
This paper briefly summarizes original and published data on the Kairagach deposit, including its geological
features and ore characteristics, sequence of the mineral formation, and the main mineral assemblages.
Occurrence conditions and chemical peculiarities of the essential minerals of the
gold-sulfide-selenide-telluride mineralization are considered. Data on the abundance and compositional variations
of native elements (gold, tellurium, and tin), fahlores, Bi and Sb sulfosalts, Cu and Fe sulfostannates, and
various selenides and tellurides are presented.
It is shown that the unique diversity of the ore mineralization is determined by the variety of state and occurrence
forms (native, isomorphous, sulfide, selenide, and telluride) of their contained chemical elements. читать далее...

Cavitation model of mineral microspherula formation in hydrothermal ores, p. 57 - 63
The cavitation model was considered to explain mineral microspherula formation conditions in ores of hydrothermal genesis. Microspherulas are treated as hardened and crystallized drops of melt. Thermodynamic calculations of thermal energy emitted during microseconds at gas bubble contraction in boiling up hydrothermal solution show that fusion of such refractory substances as quartz and gold is possible. читать далее...
