“Mineralogical Museums and Collections” section contains articles on collections and exhibits of Fersman Mineralogical Museum RAS: on the collection of mining engineer I.N. Kryzhanovsky; on Faberge Eggs from the funds of this museum (including a describing of symbols on the box with these eggs); on the exhibition devoted to A.E. Fersman’s 125th anniversary and to 80 years of the first edition of his famous book “Amuzing Mineralogy” and the review of Fersman Mineralogical Museum acquisitions in 2006–2008. This section includes also some examples from the history of discovery of national deposits by collection’s specimens. In “Personalities” section there is article on A.E. Fersman’s Uralian expeditions and on his role in the organization of the Ilmeny State Reserve; arcticle on the life and the activity of Professor G.P. Barsanov, the director of the Fersman Mineralogical Museum in 1952–1976. “Mineralogical Notes” section is devoted to Fe-dominant Bogdanovite from cementation zone of the Aginsky goldtelluride deposit, Kamchatka; and on the find of Mackinawite inclusions in grossular at the Talnakh Achtarandite locality.
In “Discussions” section there is a paper on problems of species formation in mineralogy where minerals of variable composition and with variable structure are discussed on the example of eudialyte-eucolites. The volume is interesting for mineralogists, geochemists, geologists, collaborators of Natural History museums, collectors and minerals-amateurs.

Nalivkinite Li₂NaFe²⁺₇Ti₂(Si₈O₂₄)O₂(OH)₄F, a New Mineral of the Astrophyllite Group from the Darai-Pioz Massif, Tadjikistan, p. 5 - 12

Nalivkinite, a new astrophyllite-group mineral, was discovered in the moraine of the Darai-Pioz alkaline massif located at the intersection of the Zeravshansky, Turkestansky and Alaisky Ridges, Tadjikistan. Nalivkinite occurs in the amphibole-quartz-feldspar rock in association with calcybeborosilite-(Y), bafertisite, jinshajiangite, zircon and thorite. Nalivkinite is brown with a bronze hue and a vitreous luster; in thin plates, it is transparent. Mohs hardness is 3, D_meas. = 3.32(2) g/cm³, D_calc. = 3.315 g/cm³. It is biaxial positive, n_p = 1.703(2), n_m = 1.716(2), n_g = 1.745(2), 2V_meas. = +68(2)°, 2V_calc. = +68.6°. Nalivkinite is triclinic, space group P1, a = 5.3745(6) Å; b = 11.9299(15) Å; c = 11.6509(14) Å; a =113.325(3)°, b = 94.524(2)°, g = 103.080(2)°, V = 656.2(2) Å3, Z = 1. Cell dimensions refined from X-ray powder diffraction data are as follows: a = 5.3707(2) Å; b = 11.9327(5) Å; c = 11.6546(4) Å; a =113.384(1)°, b = 94.547(1)°, 103.047(1)°, V = 655.85(2) Å3. The strongest reflections in the X-ray powder diffraction powder pattern are as follows: [(d, Å), (I, %), (hkl)]: 10.56 (100) (001), 3.50 (100) (003), 2.780 (80) (1–42), 2.648 (45) (211), 2578 (70)(130), 2.474 (15) (212), 2.295 (30) (131), 2.106 (35) (142), 1.760 (30) (133), 1.660 (15) (0–73). The infrared spectrum of nalivkinite is similar to that of astrophyllite, and the strongest lines are as follows (cm–1): 3600, 1621, 1077(sh), 1056, 975, 929, 696, 649, 566, 441, 438. The chemical composition (electron microprobe, wt. %, Li₂O and Rb₂O by ICP OES, H₂O by the Penfield method): Al₂O₃ – 0.67, SiO₂ – 35.92, TiO₂ – 10.50, Nb2O5 – 1.68, CaO – 1.29, MgO – 0.09, MnO – 5.26, FeO – 32.76, Na₂O – 1.62, K₂O – 2.49, Li₂O – 3.76, Cs₂O – 1.40, Rb₂O – 0.85, H₂O – 3.13, F – 0.75, -O=F₂ – 0.32, total – 100.04. The empirical formula of nalivkinite is (Li_1.03K_0.69Cs_0.13Rb_0.12)_1.97(Na_0.69Ca_0.30)_0.99(Fe²⁺_5.97Mn_0.97Mg_0.03)_6.97(Ti_1.72Nb_0.16Zr_0.08)_1.96[Si_7.83Al_0.17]₈O_25.98OH_4.07 (F_0.52OH_0.48)_1.00 and the ideal formula is Li₂NaFe²⁺₇Ti₂(Si₈O₂₄)O₂(OH)₄F. The crystal structure of nalivkinite was refined to an R1 index of 6.26%. The name honors Dmitry Vasiljevich Nalivkin, a famous Russian geologist (1889–1982), author of numerous works on the geology, stratigraphy and paleontology of Central Asia. The holotype sample of nalivkinite is deposited at the Fersman Mineralоgical Museum, Russian Academy of Sciences, Moscow. читать далее...
