The other chalcogenides are subordinate however among them there occur both rather rare minerals (jaipurite CoS and westerveldite FeAs – the first finds in Russia, tungstenite WS<sub>2</sub> – the first find in Khibiny) and geochemically unique objects – edgarite FeNb<sub>3</sub>S<sub>6</sub> and Ti-bearing iron sulphides. Pyrite, marcasite, alabandite, chalcopyrite, sphalerite, lö llingite, galena, cubanite, pentlandite also occur. The irregular distribution of sulphides in fenites (from 0.0 up to almost 70%) is due to the primary sulphur content in the protolith (Precambrian alumina-rich schists) which is considered to be its source. Activity of S<sup>2-</sup> in some areas of the fenites reaches the record values for the Earth objects, which results in unique mineral associations with sulphides containing Mn, W, V, and even Nb, Ti, Cr.

The formation of the sulphides in alumina-rich fenites in general took place at high temperatures (> 500–600°C) and high reducing potential. | ||

Aleksandrovite, KLi3Ca7Sn2[Si6O18]2F2 – a new tin mineral, p. 5 - 16
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 visible 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 vitreous 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, optically 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 monoclinic, 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).

IR spectrum of aleksandrovite is similar to that of baratovite, the strongest absorption strips are: 1083, 1024, 974, 950, 673, 607, 568, 520, 470, 440 cm-1. 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). читать далее...

Irarsite discovery in copper-nickel ores of Shanuch deposit (Kamchatka), p. 23 - 27
In sulfide copper-nickel ores of the Shanuch deposit (Kamchatka) new for this deposit mineral – irarsite was found. The deposit is associated spatially and geneticly with stocks and dikes of the Dukukskiy basite-hyperbasite complex of Eocene age. Three mineral associations are distinguished in its ores: pentlandite-pyrrhotite, magnetite-chalcopyrite-pyrrhotite and pyrite-marcasite one. It is established, that irarsite forms microinclusions in sulfoarsenides, more seldom in pentlandite of magnetite-chalcopyrite-pyrrhotite association of massive sulfide ores. In irarsite composition there are constantly admixtures of iron, nickel and cobalt, sometimes of rhodium and platinum. читать далее...

Chalcogenide mineralization in the alumina-rich fenites of the Khibiny alkaline complex (Kola Peninsula, Russia), p. 33 - 49
Apoxenolithic alumina-rich fenites in the Khibiny alkaline massif (Kola Peninsula, Russia) contain various and specific chalcogenide (mostly sulphide) mineralization. Chalcogenides occur mostly in essentially nephelinefeldspar rocks with variable quantities of other minerals (biotite, rutile, hercynite, corundum, ilmenite, pyrophanite, graphite, sillimanite, sekaninaite, native iron etc.). The most abundant are members of the pyrrhotite-troilite series, in some areas molybdenite is predominant. The other chalcogenides are subordinate however among them there occur both rather rare minerals (jaipurite CoS and westerveldite FeAs – the first finds in Russia, tungstenite WS2 – the first find in Khibiny) and geochemically unique objects – edgarite FeNb3S6 and Ti-bearing iron sulphides. Pyrite, marcasite, alabandite, chalcopyrite, sphalerite, lö llingite, galena, cubanite, pentlandite also occur. The irregular distribution of sulphides in fenites (from 0.0 up to almost 70%) is due to the primary sulphur content in the protolith (Precambrian alumina-rich schists) which is considered to be its source. Activity of S2- in some areas of the fenites reaches the record values for the Earth objects, which results in unique mineral associations with sulphides containing Mn, W, V, and even Nb, Ti, Cr. The distribution analysis of metals (species-defining and “macro-impurities”: from 0.n to n wt.%) among oxygen compounds and sulphides resulted in an empiric seguence of chalcophility decrease, i.e. affinity to S2- (and, correspondingly, increase of lithophylity) of metals: Cu,Pb,Mo → Zn → Fe → Mn,W,V → Nb,Cr → Ti → Mg,Ca → Al,Be,REE. The formation of the sulphides in alumina-rich fenites in general took place at high temperatures (> 500–600°C) and high reducing potential. читать далее...

Features of arsenosulvanite from the Lebedinoe deposit, Central Aldan, p. 50 - 59
The results of examination of arsenosulvanite from the Lebedinoe deposit are discussed. The comparison with available published data of arsenosulvanite and colusite indicated that arsenosulvanite studied here is significantly different from colusite in both content of species-forming minerals and set of admixtures. Based on the electron microprobe data, X-ray diffraction study, and taking into account data by FrankKame netskaya (2002) that arsenosulvanite and colu site are two structural modifications of compound V2Cu24As6S32, we conclude arsenosulvanite as independent and incorrectly discredited mineral species (Burke, 2006). читать далее...
