Abstract. The Nart Khamyts is a prominent figure predominating in the Ossetian Nartiade, who is not devoid of genuine dignity and miraculous power. However, according to the plot of most legends (“The Narts’ nykhas”, “How Syrdon made the fandyr”, etc.), Khamyts is represented as a mediocre warrior, who has not performed any feats and is inferior to his twin-brother Uruzmag in terms of courage and responsibility. Narts spoke unflattering things about him: a tendency to gluttony, hardheartedness, seduction of women, the owner of a wonderful "Arkiz tooth". However, he did not dispute the validity of such estimates. Meanwhile, the unreasonableness and vindictiveness of Khamyts, having tragic consequences, is turning good for the Narts. So, he left his mother’s crypt unattended, where in the meantime Satána, the first of the earthly horses Arfan and the first of the earthly dog Silam came into the world. And the extermination of Syrdon’s family resulted in the invention of the musical instrument fandyr. The fact that Khamyts was struck by the “female disease” makes him related to the Scythian enareas and even more to the legend of the fairy Mach from the Irish legend of the Ulaid.

Abstract. The article is devoted to the problem of the ancestor cult among the Alans. Written sources and archaeological data help build connection of this cult with funeral and memorial rites and idolatry. The continuation of the corresponding cult tradition of the Alans is presented among the materials of the traditional culture of the Ossetians.

Abstract. The article is devoted to the analysis of the state of migration processes in the Orenburg region in the post-Soviet period. From 1991-2019 the number of migrants, the direction of migration flows and their causes at the level of Russia, the Volga Federal District and the Orenburg Region underwent significant changes. The motives of migration have changed - from political to economic ones, the vector of migration in the early years of the post-Soviet period has changed from the Baltics to Central Asia. The study presents quantitative indicators of migration at the country and region level and considers the causes of migration and the changes that have occurred in them.

Abstract. Apart from field-oriented research and analytical laboratories, the building of the Institute of Geology of Ore Deposits, Petrography, Mineralogy, and Geochemistry of the Russian Academy of Sciences (IGEM RAS) also houses also the Library of Geological Literature (LGL) and Ore-Petrographic Museum (OPM). LGL is the only specialized academic library of geological literature in Moscow and owns Russia’s largest collection of geological literature. LGL was actually established in 1880 as a book fund of geological literature at the Mineralogical Museum of the Imperial Academy of Sciences in St. Petersburg and developed further hand in hand with its scientific activities. In 1938, the library received the name of “The Library of the Department of Geological and Geographical Sciences. Since 1973 up to present, the library is a research department of the Library of Natural Sciences of the Russian Academy of Sciences, and is referred to as The Library of Geological Literature at IGEM RAN (the Institute of Geology of Ore Deposits of the Russian Academy of Sciences). The Ore-Petrographic Museum (OPM) at IGEM RAN possesses a contemporary systematic collection of rocks and most ore types. The history of the museum collections is closely related to St. Petersburg’s Kuntskammer. The start of the petrographic museum collection was made by V.I. Vernadsky in 1908. Archive materials and collections of OPM, whose history of preservation stretching back over 200 years, are of undoubted academic interest. The Ore-Petrographic Museum at IGEM RAN and the Library of Geological Literature of BEN RAN extent scientific and humanitarian relations with a broad circle of museums and institutes specializing in the field of geology and natural science, first and foremost, with academic institutions, with which are connected through common historic

Abstract. The research relevance: revealed additional evidence of the need for complex disposal of buried industrial waste with preliminary extraction of economically valuable, including noble and environmentally dangerous metals; revealed a high degree of soil contamination in the valley of the Khanikom-don river. The research objective based on geochemical data is to determine the extent and degree of soil contamination in the territory adjacent to the Fiagdon tailing dump. In the article, based on the results of geochemical studies with quantitative methods (XRF and ICP MS) of soils of agricultural lands (orchards) in the Kurtat and Mountain Dzuarikau settlements and from natural pastures, estimated the extent and magnitude of contamination by industrial wastes stored in the Fiagdon tailing dump. Data on the content of economically valuable and environmentally dangerous elements in the soils of vegetable gardens and natural pastures are presented for the first time, and the geochemical role of soil-forming mudstones of the lower Jurassic age in the formation of soils is considered. It is shown that the mechanism of soil contamination is caused by wind erosion of the surface layer of the tailing dump, and then from catastrophic craters on its surface. In addition, based on the results of analyses showing sharply increased content of base metals in mudstones (Fe, Cu, Zn, Ba, Pb, As), it is suggested that there is another natural source of soil contamination of NP - soil-forming mudstones. Because during the long-term formation of NP soils in mountain conditions, they may well have been enriched with the above-mentioned base metals. It is emphasized that the presence of high concentrations of base metals in the lower Jurassic mudstone column made it possible to assume that these metals could be mobilized using the «convective cell» mechanism according to the lateral-secretion hypothesis, from the black-shale mudstone column with the formation of industrially significant ore vein bodies of the Kadat and Kakadur polymetallic deposits.

Abstract. On the basis of route surveys data in 2008, 2010, 2016 and 2017, decryption of space images from 2015 to 2019 and aerial photographs from 1957 to 1988, the paper considers the activity of dangerous natural processes in the Yusengi Valley: mudflows, landslides, avalanches and rockslides. When comparing aerial photographs of 1983 and 1988, the fact of the rockslide from the slope of the mountain Gogutai (3 753 m) is revealed. On the basis of the relief analysis of the right slope of the valley, landslides masses that are known in literature as seismogenic have been identified. The activity of mudflow processes was determined by the change in the contours of the zones of the mudflow deposits on the three debris cones and by the changes of the stream course in the wide floodplain area. The facts of the avalanche collapse were established as a result of the comparison of space images and their GIF animations taken at different times, which carried out in terms of the avalanche snow-patches presence during the spring and summer period, considering the nature and habitat of vegetation, and also the unique space image taken at the very moment of the avalanche collapse. The borders of avalanche catchments were determined on the basis of a map of slopes in comparison with the local terrain, photographs from route surveys and ontours of avalanche deposits on space images. A total of 60 avalanche catchments (including more than 200 avalanche paths), with a total area of 23.4 km2, have been isolated.

Abstract. The article provides a critical review of literature data on glaciers and periglacial lakes located in the Bartuydon River Basin (the left tributary of the Karaugomdon River, the left tributary of the Terek River) and the changes they have undergone over the past 53 years. In 1966 there used to be 6 glaciers and 1 lake. There are14 glaciers and 6 lakes now. The paper provides a forecast of possible natural processes that may occur here.
