Chernik; on the story of one exhibit from the Museum – a black basalt with a golden monogram; and also there is in this section a description of the mineralogical collection of the GeoMuseum, Cologne University, Germany.
"Personalities" section includes the article on the exhibition "Jubilees and Their Heroes"; this exhibition was devoted to 290 years of Fersman Mineralogical Museum and other jubilees concerning with the Museum. Two more articles are devoted to Professors Alexander A. Godovikov and Georgiy P. Barsanov who had leaded this Museum in different periods.
In "Mineralogical Notes" section two articles are published. First, on carbonates in metakimberlite, Zarnitsa pipe, and second, on the twisted filiform magnesian calcite from rocks at Russian platform. The volume is interesting for mineralogists, geochemists, geologists, curators of Natural History museums, and collectors.

Faizievite, a new sodiumpotassiumcalciumlithium titanosilicate, was found in a quartz boulder in association with pectolite, baratovite, aegirine, polylithionite, leucosphenite, fluorite, etc. on a moraine of the Darai-Pioz glacier, Tadjikistan. It is colourless with a strong vitreous lustre, forms tabular plates without vicinal forms, and up to 0.3 cm in maximum dimension. Mohs hardness is 4–4.5, measured density is 2.83(2) g/cm³, calculated density is 2.819 g/cm³. Faizievite is optically positive, biaxial, n_p = 1.651(2), n_m= 1.655(2), n_g =1.657(2), 2V_meas. = -72(2)°, 2V_calc. = -70.4°. The crystal structure was refined to an R index of 7.5%. Faizievite is triclinic, space group P-1, cell dimensions: a = 9.8156(9)Å; b = 9.8249(9)Å; c = 17.3087(16)Å; a = 99.209(2)°, b = 94.670(2)°, g = 119.839(1)°, V = 1403.7(4)Å³, Z = 1. The strongest lines of the X-ray powder diffraction pattern are as follows: [d, Å, (I, %), (hkl)]: 5.60 (9) (0 0 3), 4.25 (60) (0 -2 1), 3.35 (100) (0 0 5), 3.14 (20) (1 -3 2), 3.06 (90) (-1 -2 3), 2.885 (55) (-2 1 5), 2.870 (10) (-2 3 2), 1.868 (17) (-1 4 4). The strongest lines of the IR absorption spectra are as follows: 1211, 1178, 1130, 1022, 940, 783, 683, 651, 557, 534, 460 cm¹. The chemical composition (microprobe, excepting data for Li₂O, Rb₂O, BaO, SrO – which was obtained by ICP OES, wt.%): SiO₂ – 60.65, CaO – 14.52, TiO₂ – 13.44, Nb₂O₅ – 0.11, SrO – 0.72, BaO – 0.24, K₂O – 3.93, Na₂O – 1.99, Li₂O – 3.76, Rb₂O – 0.13, F – 1.30, -O=F₂ – 0.55, total – 100.24. The empirical formula of faizievite is (K_1.98Rb_0.03)_2.01(Na_0.90□_0.10)_1.00(Ca_6.16Na_0.63Sr_0.17Ba_0.04)_7.00(Ti_4.00Nb_0.02)_4.02 Li_5.98Si₂₄O_66.00(F_1.63O_0.36)_1.99. The ideal formula is K₂Na(Ca₆Na)Ti₄Li₆Si₂₄O₆₆F₂. The name honors Faiziev Abdulkhak Radzhabovitch (born 1938) of Dushanbe, Tadjikistan, professor and membercorrespondent of the Academy of Sciences of the Republic of Tadjikistan. He is a wellknown mineralоgist, and author of numerous works on the mineralоgy and geochemistry of Central Asia. The sample with faizievite is stored in Fersman Mineralоgical Museum, Russian Academy of Science (Moscow). читать далее...

Nikita V. Chukanov, Daniel Atencio, Alexander E. Zadov, Luis A.D. Menezes Filho, Jose M.V. Coutinho. Guimarã esite, a New Zn-dominant Monoclinic Roscherite-group Mineral from Itinga, Minas Gerais, Brazil, p. 11 - 15

Guimarã esite¹, Ca₂(Zn,Mg,Fe)₅Be₄(PO₄)₆(OH)₄·6H₂O,monoclinic, is a new member of the roscheritegroup. It occurs as a late fracturefilling mineral in a phosphaterich granite pegmatite near the Piauí river, Itinga county, Minas Gerais, Brazil. Associated minerals are: albite, microcline, quartz, elbaite, lepidolite, schorl, eosphorite, moraesite, saleeite, zanazziite, an irondominant roscheritegroup mineral, opal. Guimarã esite forms peripheral zones (up to 0.1 mm thick) in crystals of roscheritegroup minerals. The inner zones of the crystals are Mgrich (and correspond to zanazziite) or Ferich (greifensteinite and/or ruifrancoite). Its colour is brown, the streak is white and the lustre is vitreous. Guimarã esite is transparent and nonfluorescent. Density (calc.) is 2.963 g/cm³. The mineral is biaxial (-), α 1.596(2), β 1.600(2), γ 1.602(2) (589 nm). 2V(obs.) 5575°, 2V(calc.) 70°. The optical X axis coincides with the elongation direction, dispersion: none observed. It is colourless under the microscope. The chemical composition is (wt. %, ranges are indicated in brackets; EDS mode electron microprobe): CaO 9.72 (9.619.79); MgO 4.00 (3.614.74); MnO 2.18 (0.893.26); FeO 2.65 (1.404.45); ZnO 19.06 (16.3320.50); Al₂O₃ 1.70 (1.531.92); BeO (calculated) 8.975; P₂O₅ 38.20 (37.6137.78); H₂O (calculated by difference) 13.515, total 100.00. The empirical formula based on six (PO₄) groups per formula unit is Ca_1.93(Zn_2.61Mg_1.11Fe²⁺ _0.41Al_0.37Mn_0.34)_∑4.84Be_4.00(PO₄)_6.00(OH)_3.90·6.41H₂O. The strongest reflections of the powder diffraction pattern [d, Å (I, %) (hkl)] are: 9.98 (90) (110), 5.98 (100) (020), 4.82 (80) (310), 3.152 (90) (202), 3.052 (70) (421), 2.961 (70) (040, 202), 2.841 (70) (312), 2.708 (80) (041). Unit cell parameters refined from powder data are a = 15.98(1) Å, b = 11.84(2) Å, c = 6.63(1) Å, β = 95.15(15)°, V = 1249.4(34) Å3, Z = 2. The space group is C2/c. The name is for Djalma Guimarã es (18951973), in recognition of his outstanding contributions to Brazilian mineralogy and geology. Holotype specimen of guimarã esite is deposited in the Museu de Geociê ncias, Instituto de Geociê ncias, Universidade de Sã o Paulo, Brazil, registration number DR 591. читать далее...
