... Deep seismic stratigraphic sections (Fig. 4) clearly show the parallel-layered shelf Kungurian series passing into deformed rocks in the central part of the basin, losing their bedded structure and having been affected by halokinesis processes, and forming domes 2-4 km wide, the internal structure of which cannot be reconstructed using seismic and geological data. Even though the sequence of rhythmic units and even their number are interpreted differently by different researchers, it is possible to compare the alternating carbonate and sulfate packages of the Kungurian Stage (especially the packages at the top of the Irenian Horizon in the Kungurian Stage stratotype) with the rhythmic packages of the peripheral parts of the Pricaspian Depression, the general structure which are shown in Fig. 5 (for details see : Stepanov, 1951;Tikhvinskaya et al., 1967;Chuvashov and Dyupina, 1973 , 1974;Sofronitsky and Zolotova, 1988;Chuvashov et al., 1990Chuvashov et al., , 2002Sofronitsky and Ozhgibesov, 1991;Chuvashov, 1997;Naugolnykh, 2007Naugolnykh, , 2017Naugolnykh, , 2018Naugolnykh, , 2020. This comparison is confirmed by the general sequence of paleogeographic events that took place within the entire western side of the Urals during the Permian period. ...
