The results of the study of the resource potential of Lelchitsky and adjacent regions are presented. It is shown that the raw materials for the production of crushed stone and natural stone in the amount of 1 million m3 is actively extracted in the region with the prospect of volume increasing up to 10 million m3. In addition, peat and sapropel are mined for the production of organic fertilizers, feed additives and drilling fluids. Brown coal and bentonite clay deposits are promising for mining. Peat, sapropel and brown coal should be considered to be raw materials for complex deep processing with the release of more products and materials with high added value. The obtained results allow to conclude that the development of Lelchitsky region and the economic feasibility of building Polesie section of the railway is possible only through integrated development and the most complete use of the entire resource base of the region.

Research subject. The weathering crust of Proterozoic slates in the Neklya River basin and Paleozoic granites in the Nizh- neselemdzhinsky gold-bearing node (NGBN) in the Tatarka River basin.Methods. The research was carried out using the methods of atomic absorption, X-ray fluorescent and mineralogical analysis of rocks and minerals. The method of raster electron microscopy was used to study the element structure, morphological and microstructural features of minerals.Results. Specific features of native gold from the weathering crust of NGBK were defined. It was established that the NGBN weathering crust contains both hypogene gold, partially changed in the course of hypergenesis, and neogenic gold. A considerable share of gold is of high purity (1000%o). Occasionally, gold in the form of complex accretions from grains of different morphology and structure is present. A specific feature of weathering crust gold is its interpenetrations within the rock matrix of a varying mineral structure. Gold-bearing carbonaceous structures in the form of films and outgrowths on gold grains were revealed; the presence of carbon in rock components associating with the noble metal was defined. In the crust, the participation of carbon in physicochemical processes was established, as a result of which the release of Au, encapsulated in minerals-concentrators, and its redeposition on geochemical barriers occur. Gold nanoparticles can be long-acting growth centres in the host rocks, first coalescing with each other to yield nanoformations, then microforms, etc. In the weathering crust of gold deposits, both the transformation of the hypogenic noble metal and the formation of its new forms occur.Conclusion. This work contributes to the expansion of the mineral resource base of gold in the Amur Region, including through such unconventional sources as the NGBN weathering crust.

University Training

Introduction. In the 1920s and 1930s, the USSR accumulated significant experience in pre-university training for young people, some elements of which remain relevant to this day. In domestic historical science, special attention was paid to the analysis of the phenomenon of workers’ faculties, which played a huge role in our country in the formation of the Soviet intelligentsia. However, at the regional level, to date, there is not a single special study, which would comprehensively consider the issues of the emergence and activities of the Mordovian workers’ faculty. This article attempts to partially fill this kind of “white spot” in the latest historiography of the history and culture of the Mordovian region and people. Materials and Methods. The main resource base of the study was made up of materials from the funds of the Central State Archives of the Republic of Mordovia (CSA RM), most of which are introduced into scientific circulation for the first time. The methodological basis for the analysis of the collected factual material was both general scientific research methods (analysis, synthesis, induction, deduction, etc.) and special historical methods: descriptive (ideographic), historical-genetic, problem-chronological, historical-systemic. Results. The author reveales the reasons for the creation of the Mordovian workers’ faculty as the main form of pre-university training in Mordovia in the 1930s, shows the dynamics of its student body; analyzes the state of the educational process and extracurricular work at the workers’ faculty; gives the characteristic features of the financial situation, everyday life and life of Mordovian students-workers of the faculty. Conclusion. The creation of the Mordovian Workers’ Faculty at the end of the 20s of the last century was an adequate response to the urgent vital need of the young Mordovian statehood for its own highly qualified personnel. With all the minuses and shortcomings in its activities, the workers’ faculty has become the main “forge of applicants” from workers and peasants for the higher school of Mordovia, a kind of “forerunner” of the preparatory department and the faculty of pre-university training and secondary vocational education of Ogarev Mordovia State University.

Composition Structure

Environmental heterogeneity across savanna landscapes, including different seasonal resources at different distances to water, may play a critical role in maintaining the size and diversity of wildlife populations and the sustainability of their resource base. We investigated whether extensive landscapes with functionally diverse seasonal resources and large waterless regions can mediate the effect of herbivory on plant composition, structure and diversity. Vegetation composition, structure and richness in two different vegetation types (mopane and sandveld woodland) at three distance zones (0 km – 5 km, 10 km – 15 km and > 20 km) from the permanent water of the Okavango Delta and Linyanti Swamps were surveyed. We modelled vegetation response of the most abundant species to herbivory in relation to distance from permanent water, and included fire frequency as a covariate. Trees favoured by elephants during the dry season occurred typically as immature, pollarded populations within 5 km of permanent water sources while mature tall populations of these species were found far from water (> 10 km – 15 km). Similarly, short high-quality grazing grasses were higher in abundance within 5 km of permanent water, whereas taller high-quality perennial grasses peaked in abundance beyond 20 km from permanent water. Trends in herbaceous richness with distance from water were contingent upon vegetation type, while tree richness did not change with distance from water. Spatial refuges in waterless regions of landscapes facilitate the creation of heterogeneity of vegetation structure, composition and richness by large herds of mammalian herbivores. Therefore, the extension of herbivore dry season foraging range, for example, by the creation of artificial water points (AWP) in backcountry woodlands, could seriously undermine the resilience of landscapes to herbivory by reducing the availability of spatial refuges. Consequently, it reduces the resilience of herbivore and predator populations that depend on these spatial refuges. We strongly advise that future scientific work, and management and policy actions should be focused on the identification and sustaining of these spatial refuges in wildlife areas.Conservation implications: Management and policy actions should be focused on the identification and sustainability of spatial refuges in wildlife areas. Too many AWP in backcountry woodlands could undermine the resilience of landscapes to herbivory by reducing the proportion of landscapes beyond 15 km from permanent water.
