Study of the supersalt beds from the Gremyachinskoye sylvinite filed has shown the sections of both, the Permian and the Triassic beds to be curtailed relative to other areas of the Pricaspian Depression. Fragmentary parts of the Middle and of the Upper Permian beds have been revealed alongside with the Lower and the Middle Triassic, missing upper Triassic beds and the traces of the Upper Jurassic deposits.
