Stratigraphic correlations are proposed after micropaleontology (fusulinids), sismic reflexions, well logging and sedimentology. The eastern border of the Precaspian Basin exhibits during the Carboniferous, an eastern carbonated platform and a western turbiditic basin interrupted by a horst and during the lower Permian a turbiditic basin interrupted by a horst. The Preuralian Basin located eastwards shows a turbiditic basin during the Carboniferous and the lower Permian. A shifting of the depocenters is observed from the Preuralian Basin to the Precaspian Basin between the Carboniferous and the lower Permian during the western progress of the nappe structures.
