The mineral resource base is a strategic component of Russia’s economic security, being a critically important tool for strengthening the country’s position in the international arena. At the same time, economic shocks and geopolitical tensions negatively affect the investment attractiveness of geological exploration projects, which are highly important for the continuous reproduction of the country’s mineral resource base.Aim. Consideration of funding possibilities for geological exploration activities in Russia.Objectives. 1) To analyze the structure and state of geological exploration funding in Russia over the past five years; 2) to study the prospects and possibilities of attracting investments for different geological exploration stages in Russia; 3) to offer new methods and tools for optimizing the funding of geological exploration activities under the conditions of transformation of the Russian economic system.Materials and methods. The research materials included domestic and foreign scientific publications; reports and publications of the Federation Council Committee on Agriculture and Food Policy and Environmental Management of the Russian Federation, the Ministry of Natural Resources and Environment of the Russian Federation, the Federal Subsoil Resources Management Agency; the results of the “Geology, Revival of a Legend” initiative; McKinsey and OECD Global Forum on International Investment analytical materials. The materials were analyzed using a set of general and specialized scientific methods. Among them are statistical modeling and forecasting to assess the state and prospects of geological exploration funding in Russia; comparative analysis and synthesis, induction and deduction to study international experience in attracting alternative investments for geological research.Results. Proposals concerning the possibility of attracting additional funding at various stages of geological exploration through the creation of direct investment trust funds are formulated. Attention is also paid to such methods as streaming and acquisition of a fixed interest rate from production in exchange for an advance payment, which can be applied at later stages of exploration.Conclusion. New approaches and best international practices should be used to attract funding for various stages of geological exploration activities in Russia. This will make it possible to attract non-governmental resources, diversify methods of financial support, as well as to increase the investment attractiveness of geological exploration projects.","PeriodicalId":508654,"journal":{"name":"Proceedings of higher educational establishments.

Systematization of data and statistical generalization, partial borrowing of materials from field data, reference literature and published materials.Results. As a result of the research, recommendations are given to reduce geological risks, assessment of promising sites, comparative characteristics of resource assessments of the research area. The significant potential of the Okhotsk Sea area may be associated with the lower (Eocene) structural floor. However, these estimates are based on encouraging, but far from complete geochemical information about the potential of the oil and gas mother strata.Conclusion. It is necessary to carry out an audit of the existing seismic data from the point of view of vertical resolution and establish the current seismic study. Taking into account this information, design and perform additional volumes of 2D seismic exploration sufficient to solve the set geological tasks, the main of which is the construction of a detailed structural framework of the sedimentary cover. The second most important geological task is a large-scale study of the geochemical properties of the organic matter of the rocks of the Eocene part of the section (in outcrops, wells), establishing changes in these properties depending on the paleogeographic situation for their more correct extrapolation to the water area.","PeriodicalId":508654,"journal":{"name":"Proceedings of higher educational establishments.

The coal-bearing deposits of the Kopsel formation of the Bathonian-Callovian age of the Middle Jurassic near the city of Sudak (Crimea) are studied. The conducted lithological and mineralogical analysis of rocks, mainly sandstones and siltstones, with shell detritus, plant residues and coal lenses (gagates), made it possible to determine the coastal-marine and lagoon sedimentation conditions. The studied gagates are represented by structural vitrinite and belong to the humus group. Secondary minerals in coal seams and host rocks indicate the stage of early catagenesis. The botanical analysis revealed the coal-forming plants, belonging to a group of conifers of the araucaria family.Aim. To identify the facies-climatic and landscape conditions for the formation of gagates of the Kopsel formation, along with their composition, structure, and secondary changes. To demonstrate that the material composition of coals is the wood of gymnosperms, mainly conifers, rather than algal thalli.Materials and methods. The natural outcrops of the coal-bearing deposits of the Middle Jurassic of the Bathonian-Callovian stage of the Kopsel formation in the valley of the Kopsel River near the city of Sudak (Crimea) were studied. The lenses and interlayers of brown coal — gagate — present in these deposits were of particular interest. Gagate samples were studied both macroscopically (forms and occurrence conditions in the section) and microscopically (by coal petrography methods). To this end, double-sided polished sections were examined using a polarizing microscope and a Vega3 Tescan scanning microscope. The microanalysis of chemical elements was performed using an ULTM Max (GIN) microscope attachment. Paleobotanical studies of carbonified plant residues were carried out. The structure, texture and mineral composition of the rocks were studied in thin sections using a microscope. A mineralogical analysis was carried out using a D8 Advace X-ray diffractometer (gross composition in a powder diffractogram and composition of clays in a fraction of <0.001 mm) and a Vega3 Tescan (GIN) scanning microscope.Results. The comprehensive studies conducted in the new, unique location of coals in the Kopsel Formation of the Middle Jurassic (Bathonian-Callovian stage) in the valley of the Kopsel River determined the paleobotanical composition of coal-forming plants (with the predominance of conifers of the Araucariaceae type), the climatic and paleolandscape conditions for the formation of these coals on the northern outskirts of Tethys. The lithological and mineralogical features of rocks, mainly sandstones and siltstones, with shell detritus, plant residues and lenses of coals (gagates), make it possible to determine the facies conditions of sedimentation as coastal-marine and lagoonal, with fragments of avantdelta and proluvial, landslide deposits.
