POTENTIAL FOR NEW DEPOSITS IN THE LISAKOVSK AREA BASED ON THE RESULTS OF EXTENDED GEOLOGICAL EXPLORATION

The article presents the results of geological additional study of the Lisakovsk area (sheets N-41-XXVII and N-41-XXXIII), which made it possible to significantly clarify the geological structure and prospects of ore content of this important metallogenic territory. Based on the analysis and reinterpretation of a large volume of stock and archival materials, as well as the results of our own field studies, the stratigraphic scheme of the area has been refined. For the first time in the Denisov structural-formational zone, a complex of metamorphic rocks of the Precambrian-Lower Paleozoic has been identified. The stratigraphic position of the Lisakovsk stratum of oolitic iron ores has been clarified. A digital model of the cover complex has been created, allowing for the compilation of horizon maps for all stratigraphic units. New data on the tectonic structure of the junction zone of the Denisov and Valeryanovsk structural-formational zones have been obtained. A new geodynamic model for the formation of this structure has been proposed. Minerogenic zoning of the territory was carried out with the identification of promising areas for various types of minerals. Minerogenic zones, districts, ore nodes and ore fields prospective for iron, copper, polymetals, gold, silver, and bauxite have been identified. Areas are recommended for prospecting for gold-copper-porphyry, pyrite-polymetallic, gold-quartz-vein types of mineralization. The Northern and Alakolsky-1 areas are designated as priority sites. The obtained results provide a reliable basis for further study of the territory and targeted exploration work in the identified promising areas.
