Shendrik R.Y., Plechov P.Y., Smirnov S.Z. ArDI – the system of mineral vibrational spectroscopy data processing and analysis, p. 26-35

ArDI (Advanced spectRa Deconvolution Instrument) is a web-application for processing and analyzing of vibrational spectra of minerals (https://ardi.fmm.ru/). It is designed for express and reliable identification of minerals in geological samples. ArDI allows processing of spectra, searching for similar spectra in databases, and loading reference spectra into the database for its expansion. ArDI has prospects for development in several directions, including the improvement of the interface ergonomics and further development of algorithms for automatic processing of Raman spectra, filling the database with reference spectra, and integration the reference spectra database with the information system of Fersman Mineralogical Museum of the Russian Academy of Sciences and other mineralogical information systems. ArDI can be used for quick identification of minerals and interpretation of separate spectral bands. It can be useful in mineralogy, the examination of raw materials and gemstones, as well as in medicine, pharmacy, and criminalistics.

Spiridonov E.M., Ovsyannikov G.N. Pseudomorphs of pseudobrookite and pseudorutile, titanite, rutile after armalcolite, ilmenite and titanomagnetite in low-grade metamorphosed intrusive rocks of the Mountain Crimea, p. 36-45

Rocks of the island-arc pervomaisko-ayudag intrusive complex of Mountain Crimean mesozoids from plagiolherzolites to quartz gabbro-norite-dolerites and from quartz diorites to plagiogranites contain a noticeable amount of titanium minerals. There are chromtitanomagnetite and armalcolite in olivine-bearing rocks, whereas ilmenite and titanomagnetite are in all types of gabbroids and plagiogranitoids. Under the conditions of prehnite-pumpellyite facies in intensively metamorphosed igneous rocks armalcolite, ilmenite and titanomagnetite replaced titanite (at a distance from the contact with metamorphosed sedimentary rocks, a source of carbon dioxide and sulfur during metamorphism) or pseudobrookite and pseudorutile (near the contact with metamorphosed sedimentary rocks). Subsequently, part of pseudobrookite and pseudorutile were replaced by rutile, then rutile + pyrite. Titanite composition is (n = 3): Ca_1.00–1.02(Ti_0.76–0.92Fe³⁺_0.04–0.07Al_0–0.17V_0.01–0.02)_0.98–1[(O_0.78–0.90ОН_0.22–0.10)₁/Si_1.00–1.01O₄]. Composition of pseudobrookite is (n = 8): ((Fe³⁺_1.74–1.95Al_0–0.07V_0–0.03)_1.82–1.96(Mg_0–0.08Mn_0–0.02Zn_0–0.01)_0.02–0.09Ti_1.02–1.09O₅; minal content, mol.%: pseudobrookite 91.1–98.0; armalcolite 2.0–8.9. Composition of pseudorutile is (n = 4): (Fe³⁺_1.80–1.95Al_0–0.11V_0.03–0.04Mn_0.01–0.02Mg_0–0.01)_1.99–1.97Ti_3.01–3.03O₉. There are no titanite, pseudobrookite, pseudorutile, rutile, hematite, and pyrite in non-metamorphosed island-arc intrusive rocks. The replacement of armalcolite and ilmenite by pseudobrookite and pseudorutile is an iron oxidation reaction, which correlates with an increased f O₂ of metamorphogenic fluid. Thus, a metamorphogenic-hydrothermal genetic type of pseudobrookite and pseudorutile, arosed under the conditions of the prehnite-pumpellyite facies, is described.

Generalov M.E. Zeolites from an Exile: Czekanowski’s collection from the Lower Tunguska expedition, p. 46-54

The Fersman Mineralogical Museum holds a mineral collection that was gathered 150 years ago on the Lower Tunguska River by Aleksander Czekanowski, the famous explorer of Siberia. This collection can be considered as a historical and cultural heritage. It includes one of the first mineralogical samples from the region. By comparing the samples in the museum’s collection and the explorer’s journal entries, we can (were able to) improve our understanding of the geological environment and the geographical name of the samples’ localities, as well as the history of the Museum collection’s growth in the beginning of the XX century.

The article describes the find of chrysoberyl in the Pridorozhnyi granite pegmatite (Shakhdara River, Southwest Pamir, GBAO, Tajikistan). Pegmatite with chrysoberyl is a steeply dipping. Pegmatite is weakly zoned, it is mainly of a quartz-oligoclase composition with a subordinate role of albite, K-feldspar, muscovite, shorl, spessartite-almandine series garnet. Accessory minerals are as follows: andalusite, monazite-(Ce), zircon, fluorapatite, titanite, Cs-bearing beryl and not determined W-tantalo-niobate. Chrysoberyl has occur in pegmatite as a single plate and tabular crystals; it occurs twins and less often, threelings. The size of chrysoberyl aggregations varies from 0.5 to 10 mm. The color of the mineral is yellowish-green. In a shortwave ultraviolet the mineral luminesces in yellow-orange tunes. Microhardness VHN200 = 1607. Measured density is 3.67 (2) g/cm3. Chrysoberyl unit cell parameters are a = 4.430(1), b = 9.410(1), c = 5.480(1) Å. The IR and Raman spectra of the mineral are given. The empirical formula of it is Be_1.00 (Al_1.97Fe_0.02Ti_0.01)_2.00O₄. According to LA-ICP-MS, chrysoberyl is enriched in Sn (> 1900 ppm), B (> 140 ppm) and Sc (< 100 ppm). The contents of trace elements in chrysoberyl and beryl from Pridozhny pegmatite are compared. A sample with chrysoberyl was given to Fersman Mineralogical Museum, RAS (No FMM_1_98624).

Sokolova E.L., Dokuchaev A.Ya. On scientific documentation of exhibitions of the A.E. Fersman Mineralogical Museum of RAS, p. 66-79

Data on the exhibition activities of the Mineralogical Museum from its foundation in the 18th century to the second half of the 20th century are scant and fragmentary; systematic documentation of the exhibitions has never been conducted. The situation has improved in recent decades, but documentation of exhibitions on a scientific basis according to a single model is not conducted; it has not been developed, despite the technical capabilities of our time. It is necessary to introduce into museum use mandatory scientific documentation of exhibitions in the form of a single data base, which would include topographic inventories, detailed photographs, data on auxiliary material, references to scientific works, names of authors and year of creation, data on modernization. Such documentation should be compiled not only for permanent, but also for temporary and traveling exhibitions of the museum. Without this necessary measure, we will lose information on the evolution of the museum's exhibition activities and the intellectual activity of generations of scientists who have contributed to the development of the museum.

Generalov М.E., Agakhanov А.А. The Emperor's Teacher and His Heritage. A.B. Kemmerer's Materials in the Collection of the A.E. Fersman Mineralogical Museum, p. 80-93

One of the authors of the Museum samples, Alexander Bogdanovich (August-Alexander) Kaemmerer left a noticeable mark on Russian mineralogy and mining. He studied a number of mineralogical finds, worked with various mineralogical collections, including those that later were included to the collection of the Mineralogical Museum. Under his influence, a number of minerals were named in honor of Russian statesmen. The samples with his authorship in the Museum collection are examples of early finds of a number of minerals in Russia. Samples of platinum group minerals from his collection are associated with the discovery of the first rich platinum placers from the area of the Nizhny Tagil dunite-harzburgite massif. The mineralogy of these materials was studied, and a variety of forms of decomposition of solid solutions of ferrous platinum were shown. A conclusion was made about the connection of the studied substance, mainly, with the high-temperature association of platinum group minerals of the Nizhny Tagil massif, with the deluvial-proluvial placers that have been exhausted.
