The study of the Upper Permian and Triassic sediments of the Caspian Basin has recently become increasingly important: the research area is located in the eastern instrumental zone of the salt dome area of the Caspian depression. As it is known, the intensity of the salt tectonics processes decreases as we approach the sides of the depression, up to complete attenuation in the marginal part of the basin. This is caused by the reduction of the initial thickness of the Kungur saline sediments as they move from the central parts of the basin to the periphery; changes in the petrographic composition of the sediments, in particular, enrichment of the section with terrigenous, carbonate and sulfate interlayers; the time of manifestation of the most active phases of tectonic movements ....
