The position is shown regarding the depth-density and seismic inhomogeneities of the Earth’s crust of W-Sn- and Au-ore nodes, fields, deposits; their localization on the density barrier of ore deposition. An innovative technique for studying the deep structure of the subsurface and geological forecasting of potentially ore-bearing environments is recommended, based on mapping the magmatic front of continental crust decompression ascending from the depths and sections of its (front) wedging into near-surface dense masses. Keywords: the magmatic front of the continental crust decompression, the density barrier of ore deposition, potentially ore-bearing environments of the «ore node-ore field» rank.

The richest ore bodies with magnetite mineralization are associated with retrograde skarns, where magnetite is associated mainly with actinolite/tremolite, phlogopite, garnet, and other skarn minerals. The first obtained data on the microelement composition of magnetite made it possible to establish indicator characteristics (values) for skarn and skarn-porphyry types of mineralization. Keywords: magnetite, typochemistry, skarn deposits, porphyry skarn deposits, Eastern Transbaikalia.

(Tomsk Polytechnic University) // yazikoveg@tpu.ru ROCK PERMEABILITY FACTORS AND THE APPLICATION OF INDUCTION LOGGING UNDER THE CONDITIONS OF URANIUM DEPOSITS OF BED OXIDATION ZONES FOR ORE MINING (ON THE EXAMPLE OF CHU-SARYSUY PROVINCE) The article presents the prospects for the use of induction logging, taking into account rock permeability factors, to assess the active thickness of ore-bearing rocks in hydrogenous uranium deposits (using the example of the Inkai Chu-Sarysu province). The article substantiates the effectiveness of induction logging as a standard method for monitoring the hydrodynamics of leaching solutions. The use of the method at the stage of development of hydrogenous deposits makes it possible to accurately determine the change in the active power of the technological unit, which increases the efficiency of mining ore deposits. Keywords: reservoir permeability, in-situ leaching method, active power, induction logging, hydrogenous uranium deposits, block active power control.

(TPU, Tomsk) // juliadib@yandex.ru RUSSIA LITHIUM PRODUCTS: SUPPLY AND DEMAND ISSUES The state of the Russian lithium industry is very complex due to the complete absence of national production of lithium raw materials. A commercial transit import-export process flow of lithium products from the conversion of imported lithium carbonates into oxides for export was formed. Due to political sanctions in 2022, there was a decrease in the import volume, processing and lithium products’ export, which complicated the work of the Russian lithium industry. Reconstruction of the national production of strategic lithium raw materials for the purpose of its import substitution is possible by putting into operation its hydro-mineral and mineral (spodumene) deposits. Keywords: strategic raw materials, import dependence, lithium carbonates, import, lithium hydroxides, export, national projects.
