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.

Chukhrovite(Nd), Ca3(Nd,Y)Al2(SO4)F13·12H2O, a New Mineral, p. 5 - 10
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.
