Genetic Interpretation of the Textural–Structural Appearance of Early Permian Sylvinite Rocks in the Caspian Basin

The paper presents the results of studying sylvinite rocks of the Lower Permian halogenic formation in the West and East Perelyub sites with perspectives for the commercial development of potassium salts in the Saratov region and in the Gremyachinsk potash deposit (Volgograd region, Russian Federati...

Description
Summary:The paper presents the results of studying sylvinite rocks of the Lower Permian halogenic formation in the West and East Perelyub sites with perspectives for the commercial development of potassium salts in the Saratov region and in the Gremyachinsk potash deposit (Volgograd region, Russian Federation) by the textural–structural analysis methods to refine their formation conditions. A new method is proposed for studying the structural–textural features of sylvinites and sylvite–halite rocks. Typification of sylvinite structures and identification of the main genetic types of their texture are accomplished. Based on the literature data and the results of studying the core material, a scheme of the structure–texture classification is proposed for the chemogenic-sedimentary potassic rocks, including those subjected to postsedimentary transformations.
