The paper of the chairman and vicechairman, Subcommittee for Unnamed Minerals, IMA Commission on New Minerals, Nomenclature and Classification, published earlier in Canadian Mineralogist journal, is reproduced here in brief version by request of the Commission in order to introduce the new and approved coding system as widely as possible.
"Mineral Museums and Collections" section contains information on mineral collections of Fersman Mineralogical Museum: on art things of masters from the Urals on mineral collections of the Tsesarevichs and of General G.P. 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, np = 1.651(2), nm= 1.655(2), ng =1.657(2), 2Vmeas. = -72(2)°, 2Vcalc. = -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 (K1.98Rb0.03)2.01(Na0.900.10)1.00(Ca6.16Na0.63Sr0.17Ba0.04)7.00(Ti4.00Nb0.02)4.02 Li5.98Si24O66.00(F1.63O0.36)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...

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 Ca1.93(Zn2.61Mg1.11Fe2+ 0.41Al0.37Mn0.34)∑4.84Be4.00(PO4)6.00(OH)3.90·6.41H2O.
