Abstract
Seismostratigraphic analysis of Paleogene deposits in northeastern Ustyurt was carried out. Four seismostratigraphic complexes have been recognized: Paleocene-Ypresian, Lutetian-Bartonian (Tasaran unit), Bartonian-Priabonian (Saksaul'skaya-Chegan), and Oligocene. We have established for the first time the clinoform structure of the Tasaran and Saksaul'skaya-Chegan complexes, which explains various concepts of their age. Seismostratigraphic analysis must be an integral part of stratigraphic research, which will significantly increase the reliability of correlation between geologic sequences.
