This article analyzes the history of the geological structure and the geological development of the Upper Proterozoic, Paleozoic and Mesozoic deposits of the South Torgay sedimentary basin, and determines their geodynamic stages of development based on the study of lithological and stratigraphic complexes of the sedimentary basin itself, as well as adjacent folded structures. Vendian - Early Paleozoic and Jurassic stages of rifting processes in the development are identified and described. The fundamental difference between these stages of rifting is that in the Vendian-Early Ordovician manifested themselves accordiFsing to the classical scheme with intense subsidence and extension at the early stages of development (the formation of molassoids, tillites in the Vendian, then siliceous-carbonaceous-terrigenous and siliceous-carbonate rocks) and compression, tectonic inversion, active dislocations and widespread magmatism in the final stages. At the Jurassic stage of rifting, intensive tectonic dislocations occurred in the South Torgai paleobasin, which resulted in active movements of differently oriented Paleozoic and Pre-Paleozoic faults, the split of the ancient Proterozoic-Lower Paleozoic basement, which initiated formation of grabens. However, the genesis of the graben system was completed without the introduction of magmatic bodies and intensive tectonic deformations. Thus, the South Torgay paleobasin can be considered as a zone of inherited rifting, a tectonic structure that twice survived the stages of rift development, in the Late Proterozoic-Early Paleozoic and in the Jurassic The article also presents lithological and paleogeographic maps of various geological eras based on geological and geophysical data, which confirm that the formation of the sedimentary basin and lithological and stratigraphic complexes of the South Turgay were significantly influenced by rifting processes. © 2023, National Academy of Sciences of the Republic of Kazakhstan.

Практическое значение
Практическое значение статьи заключается в возможности использования результатов геодинамического мониторинга для оценки рисков, связанных с длительной эксплуатацией Карачаганакского нефтегазоконденсатного месторождения. Полученные данные могут применяться для прогнозирования деформаций земной поверхности, выявления потенциально опасных зон, оценки влияния добычи углеводородов на геологическую среду и повышения безопасности эксплуатации нефтегазовых объектов. Результаты исследования также могут быть использованы при планировании мониторинговых мероприятий на других крупных нефтегазовых месторождениях.Квартиль
