Generalov M.E. The Fate and the Ways of the Junior Scientist Curator. Henry I. Kasperovich’s Materials in the Fersman Mineralogical Museum, p. 5-11

The article tells about the fate of Henry Kasperovich, an assistant of V.I. Vernadsky, who worked with him at Moscow University, and then followed him to the Mineralogical Museum of the Academy of Sciences.
The analysis of information on the minerals with his authorship in the Museum's collection shows that a significant part of them is connected with the first research of the Radium expedition organized by V.I. Vernadsky, and makes it possible to clarify their localities, including problematic ones related to changes in the political and administrative statuses of territories.

Pautov L.A., Mirakov M.A., Karpenko V.Yu., Makhmadsharif S. Ge-bearing cassiterite from sublimates of a natural underground fire in the Kukhi-Malik tract in the Ravat area of the Fan-Yagnob coal deposit (Tajikistan), p. 12-23

Ge-bearing cassiterite was found in the sublimates of a natural underground coal fire in the upper reaches of the Kukhi-Malik tract at the Ravat site of the Fan-Yagnob coal deposit (Aininsky district of the Sughd region, Tajikistan). Associated with cassiterite minerals are as follows: Se-bearing greenockite, anglesite, marchaninite (?) TlBi(SO₄)₂, BiCdS₂Cl, Bi₂(S,Se)₃, Cd₂InS₃F, Bi₃(S,Se)₄, In-fluoride. The listed minerals form drop-like aggregates (30–150 µm in diameter), the outer zone of which is composed of small (5–15 µm) pseudocubic cassiterite crystals. Such aggregates most often grow on greenockite crystals. Cassiterite is enriched in germanium (up to 2.3 wt.% GeO₂), antimony (up to 4 wt.% Sb₂O₅), indium (up to 2.5 wt.% In₂O₃), and is poor in titanium.

Shkursky B.B. The indicator grain misorientations for cumulate olivine ultramafites. Theoretical analysis, p. 24-37

Two types of the indicator misorientations of contacting olivine grains, expected in texturally mature cumulate dunites, are predicted. The theoretical analysis of misorientations of the both types were calculated using the Rodrigues-Frank space. The calculations of numeric parameters of the first type, corresponding to the face-to-face contacts of euhedral crystals used new formulas for compositions involving infinite Rodrigues-Frank vectors. The misorientations of the first type are mapped in the fundamental zone of the Rodrigues-Frank space by straight line segments. The misorientations of the second type associated with edge-to-face crystal contacts, are mapped in the Rodrigues-Frank space by fragments of second-order doubly ruled surfaces.

Pautov L.A., Mirakov M.A., Karpenko V.Y., Makhmadsharif S., Shodibekov M.A. Brannerite from the Eastern Pamir, p. 39-50

A crystal of brannerite UTi₂O₆ weighing 44.5 g was found on the right side of the Kukurt River in the Eastern Pamir (Gorno-Badakhshan, Tajikistan). The mineral is metamict. It gives an X-ray diffraction pattern of a mixture of brannerite, rutile and U3O8 after annealing. The chemical composition of brannerite (average over 10 microprobe analyzes) is calculated on O = 6 apfu on the formula (U⁺⁴_0.68U⁺⁶_0.13Y_0.07Th_0.05Ce_0.01Gd_0.01Dy_0.01Yb_0.01Ca_0.01)_0.98(Ti_1.89Fe⁺³_0.13)_2.02O₆. Density (meas.) 5.40(5) g/cm3. In reflected light it is light gray with moderate reflectivity (reflectance spectrum is given). The mineral is isotropic due to its metamict nature. Reflections in the air are red-brown. Microhardness VHN = 674. Raman spectrums of brannerite and its alteration products are given. The substitution products of brannerite are described briefly.

Generalov M.E. The path of mining engineer Konstantin Yegorov and its reflection in the collection of the Fersman Mineralogical Museum, p. 51-58

The article traces the connection of mining engineer Konstantin Fedorovich Egorov biography with his contribution to the Fersman Mineralogical Museum collection. His long and fruitful cooperation with the Museum and collectors gives reason to believe that Museum's collection may include more than 1643 samples for which his authorship was indicated. Behind the richest collection, gathered by him during his work in the Russian Empire and in exile, there are a number of discoveries in mineralogy, geology, paleontology, an eventful and dramatic history of the first half of the XX century.

Pavlova Т.М., Garanin V.K. Historical prerequisites for the development of Museum Affairs in Russia on the example of the A.E. Fersman Mineralogical Museum of the Russian Academy of Sciences, p. 59-70

The article briefly discusses the main stages of the early history of the A.E. Fersman Mineralogical Museum of the Russian Academy of Sciences. It is noted that in Russia an experience on the searching and mining of ores, colored stones, description of deposits and minerals had started accumulating back in the XV–XVI centuries. Reformer and educator Peter the Great established (1714) the first public science museum Kunstkamera, and the Mineral Cabinet was organized as part of it in 1716. Its collections had been attracted an attention of a numerous visitors. Public interest in the stone was also formed through amateur collecting. With the accumulation of knowledge about minerals, scientific collecting came to the fore, which served as an impetus for the development of Museum Affairs in the field of geological and mineralogical sciences. In the first half of the XVIII century, the collections of the Mineral Cabinet were sufficiently well studied, systematized and it was an independent scientifically organized assemblage, which later formed the basis of the current Mineralogical Museum of the Russian Academy of Sciences.

Sokolova E.L. Minerals and rocks of the Earth’s upper mantle in the collection of the Fersman Mineralogical museum RAS, p. 72-80

Representative collection of upper mantle rocks and minerals has been assembled at the Fersman Mineralogical museum. It counts 339 specimens. The article provides a description of the collection, the tables group data on the mineral composition and quantity of the specimens, their geographical locations and sources of acquisitions. The mantle substance is represented mainly by xenoliths of rocks and xenocrysts of minerals from kimberlites. The collection contains almost all major types of mantle rocks, as well as samples of rare mantle formations. The study of the material is rather uneven. Approximately two thirds of the collection are samples from kimberlites of Yakutia; the material from many other locations, including large deposits, such as, for example, the famous kimberlites of South Africa, is represented by a single or several specimens. Seventy four domestic and foreign researchers and organizations have donated specimens of mantle rocks and minerals to the museum for almost two centuries. Of particular note is the contribution of the famous geologist A.I. Ponomarenko, who donated to the museum a unique collection of mantle rock xenoliths, mined by him on the kimberlite pipes of Yakutia. The museum is interested in a comprehensive study of the already available material by a wide range of researchers and in replenishing the collection with new specimens of mantle rocks and minerals.

Karpenko V.Y., Pautov L.A., Agakhanov A.A., Mirakov M.A., Siidra O.I. Tapiaite from the Chauvay ore field – the second find in the world, p. 81-89

At the Obdilya Au deposit within the Chauvai ore field (Kyrgyzstan), arsenic mineralization was discovered, which contains tapiaite Ca₅Al₂(AsO₄)₄(OH)₄·12H₂O, previously known only at the Jote Mine (Chile). Mineralization is confined to the carbonate strata of the Tolubai formation (С₁–С₂) and is represented by orpiment, realgar, vladimirite, mansfeldite, talmessite, high-calcium member of the pharmacoaluminite–pharmacosiderite series, X-ray amorphous K-Ca-Fe-Al-arsenates. Tapiaite forms aggregates of white “spherulites” (100–250 µm) with a silky glance, composed of flattened prismatic crystals with forms {10 }, {101}, and {232}(?). The length of individual crystals is 10–50 µm; twins are common. The mineral is optically biaxial positive. Tapiaite crystals have direct extinction with respect to elongation, n_p = 1.578(2), n_g = 1.609(2), pleochroism is absent. The chemical composition of the central parts and rim zne of “spherulites” somewhat differs in total (microprobe, wt %; center/rim) As₂O₅ 45.42/43.39, Sb₂O₅ 0.06/0.32, SiO₂ 0.02/0.09, Al2O3 9.82/9.64, Fe₂O₃ 0.19/0.02, CaO 27.17/26.44, SO₃ 0.13/0.00,total (without H₂O) 82.83/79.90; H₂O by difference 17.17/20.10. Calculation for 11 atoms (Ca+Al+Fe+As+S) leads to the formulas Ca_4.95Al_1.97Fe_0.02[As_4.03S_0.02O₁₆](OH)_4.17·7.65H₂O for the central part of “spherulites”, and Ca_4.98Al_2.00[As_3.99Sb_0.02Si_0.02O₁₆](OH)_4.09·9.74H₂O for the rim zone. Possible reasons for the higher totals of analyzes compared to tapiaite from the place of the first description are discussed. An X-ray powder pattern of tapiaite is given for a single crystal (space group P2₁/n), the unit cell parameters are a = 16.03(1), b = 5.81(2), c = 16.32(2) Å, β = 116.7(2)°, Z = 2. Raman spectra are given both for tapiaite from Obdili and Jote. The origin of tapiaite can be connected with the near-surface discharge of waters enriched in As, as well as with the processes of alteration of primary As-minerals.
