Moscow.: Ocean Pictures, 2005. volume 40, 168 pages, 15 color and 99 b/w drawings, schemes, photos. The volume 40 includes articles on new mineral species, among which chukhrovite(Nd), tsepiniteSr, senkevichite, and kyrgyzstanite are described. The new data on rare minerals calcurmolite and turanite, easily oxidizable chalcopyrite from black smokers of the Rainbow hydrothermal field (MidAtlantic Ridge), vanadium hematite associated with minerals of precious metals, copper, zinc, and iron is given; also there is data on fahlores from the Kvartsitovye Gorki deposit and the nickelinebreithauptite mineral series from the Norilsk ore field. Features of bismuth mineralization of the Djimidon deposit (North Osetia) and raremetal mineralization connected with bituminous matters from pegmatites of the Khibiny and Lovozero massifs are revealed. The results of study of metacolloidal gold and delhayelite crystals are published. In the «Mineralogical Museums and collections» part, the minerals named in honour of collaborators of the Fersman Mineralogical Museum, specimens of platinum of the Ugolnyi stream (Norilsk) from the Museum collection are described; interesting historical data on the items of Decorative and Precious Stones collection (PDK) is given. «Mineralogical Notes» part includes the mineralogical summary of main mineral types of ores of Europe and the article devoted to mineral drawings of Victor Slyotov and Vladimir Makarenko. In new «Discussions» part, the polemics on the theme «What are the mineral and mineral species» is opened. The review of new books is published. The volume is of interest for mineralogists, geochemists, geologists, and also collaborators of naturalhistorical museums, collectors and amateur of minerals.

Bekenova Satpaev Institute of Geological Sciences KAS, Almaty, Kazakhstan, [email protected] Vladimir Yu. Karpenko Fersman Mineralogical Museum RAS, Moscow, [email protected] Atali A. Agakhanov Fersman Mineralogical Museum RAS, Moscow, [email protected] In specimens from the oxidized zone of the KaraOba deposit (Central Kazakhstan), a new neodymiumdominant analogue of chukhrovite(Y) and chukhrovite(Ce) has been found; it has been named chukhrovite(Nd). The new mineral occurs in the form of isometric grains and small crystals represented by a combination of {100} and {111} faces, with sizes ranging from 0.05 to 0.4 mm; it forms zones within the larger crystals of chukhrovite(Y) also. Chukhrovite(Nd) is associated with quartz, fluorite, halloysite, chukhrovite(Y), anglesite, gearksutite, creedite, and the jarosite group minerals. The mineral is colourless, rarely white. Streak is white. Hardness is 3.54 on Mohs' scale. Density (meas.) is 2.42(3) g/cm3, density (calc.) is 2.42 g/cm3. The mineral is transparent, and in thin sections it has anomalous grey interference colours, n=1.443(2) (589 nm). Chemical composition (electron microprobe instrument, wt %) is following: CaO – 20.03; Y2O3 – 1.94, La2O3 – 2.32; Ce2O3 – 1.37; Pr2O3 – 1.37; Nd2O3 – 6.26; Sm2O3 – 1.90; Gd2O3 – 1.12; Dy2O3 – 0.44; Ho2O3 – 0.10; Al2O3 – 12.09; SO3 – 9.38; F – 28.93; H2O (by difference) – 24.93, less O=F 12.18, total 100.00 wt%.Empirical formula is Ca3.06(Nd0.32Y0.15La0.12Sm0.09Ce0.07Pr0.07Gd0.05Dy0.02Ho0.01)0.90 Al2.03S1.01O3.96F13.06·11.87H2O. Ideal formula is Ca3(Nd,Y)Al2(SO4)F13·12H2O. Cubic, space group Fd3, a=16.759(3) Å, V=4707.0(1) Å3, Z=8. Strong lines of Xray pouder pattern are following (dI(hkl)): 9.710(111); 5.927(220); 3.228(511); 2.5557(533); 2.2405(642); 2.1806(731); 1.8275(842). The IR spectrum is as follows: 3548, 3423, 1630, 1090, 586, 465 cm1. The type specimen of the new mineral is at the Fersman Mineralogical Museum, RAS (Moscow). 3 tables, 3 figures, and 11 references.
