Early Carboniferous paleogeomorphology of SE Tataria

Abstract

The paper reports the results of detailed paleogeomorphological and lithological-facial studies of the Radaev-Bob-rikov layers at the western slope of the South-Tatarian vault and the eastern slope of the Melekess Depression. The buried landforms outlined (eleva-tion and plains) are characterised with special types of sediment sequence and oil traps. Structural-lithological traps are mostly found at plains and elevations, structural oil traps are confined to ancient erosion-accumulative plain. The regularities thus revealed may increase the oil and gas searches efficiency.
