Abstract
As part of this work, the results of a detailed study of the main lithological and paleogeographic characteristics of the rocks of the Balkhash depression are highlighted. They have a complexly constructed dynamics of the geological section with a range from Paleozoic to Quaternary sediments, with a wide development of sedimentary carbonate-terrigenous strata and significant manifestations of volcanism in the lower Paleozoic rock complex. Based on studies of the collected materials, the lithological composition of the rocks, the conditions of their formation were studied in order to justify the prospects of their oil and gas potential. The studied geological complexes in the basins are composed of volcanic-sedimentary Paleozoic rocks and terrigenous Meso-Cenozoic sedimentary deposits.
