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 min- erals (pabstite from the moraine of the Dara-i-Pioz glacier, Tadjikistan, germanocolusite from Kipushi, Katanga, min- erals of the hilairite group from Khibiny and Lovozero massifs). Results of study of mineral associations in gold-sulfide- tellyride 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 photo- graphing 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.

Hawthorne Department of Geological Sciences, University of Manitoba, Winnipeg, Canada A new mineral, telyushenkoite, was discovered in the DaraiPioz 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 2 3 hardness = 6, VHN100 = 714(696737) kg/mm , Dmeas. = 2.73(1), Dcalc. = 2.73g/cm . In transmitted light, telyushenkoite is colorless and transparent. It is uniaxial positive, ω = 1.526(2), ε = 1.531(2). Singlecrystal Xray 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 compo- sition (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 Csdominant analogue of leifite, ideally NaNa6[Be2(Si15Al3)18O39F2]. 3 tables, 2 figures and 6 references .
