The article examines the paleogeographic conditions of rock formation of the Alakol depression from the Baikol era of the end of the Proterozoic in order to determine the most favorable deposits for oil and gas source properties, where to the north and south of the Alakol depression there were marine sedimentation conditions with the accumulation of deposits up to 1000m. it was found that in the Early Cambrian time, a contract relief developed east of the depression. In the Ordovician, sediments accumulate under m...

Eastern sedimentary basins in terms of oil and gas bearing in particular the Balkhash from the point of view of oil and gas content is considered for the first time. The results presented are obtained on the basis of an analysis of the consideration of the paleogeographic conditions of the formation of the Paleozoic, Mesozoic and Cenozoic formations. The lithological composition of the sediments of the Balkhash depression is given in detail. The role of paleogeographic environments as one of the factors influencin...
