Insoluble remains of Lower Permian sylvinite rocks in the western and north-western framing of the Caspian depression

Authors: Goncharenko O. P., Solomon M. V.

The paper presents the results of a study of the insoluble residue of sylvinites and sylvin-halite rocks of the Lower Permian halogen formation, common within the Perelyubsky areas (Western and Eastern), promising for industrial development (Saratov Region) and the Gremyachinsky potash deposit (Volgograd Region). A technique for studying the insoluble residue of sylvinites is presented. The types of insoluble residue are distinguished according to the form of occurrence in sylvinites and its mineral composition is characterized.

Features of the Permian and Triassic beds in the supersalt complex from the Gremyachinskoye potassium salt field

Authors: Bukina T. P., Yanochkina Z. A., Moskovsky G. A.

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.
