Karst morphogenesis in the near-surface zone of the sulphate-carbonate massif of the Sokolino-Sarkayevskoe gypsum and anhydrite field

The gypsum and anhydrite Sokolino-Saraevskoe field located in the Kungur district of the Perm regionhas been developed since 1928. The geological structure of the field, and cavernous porosity of sulfate economic beds were studied. It is established that geological conditions of Sokolino-Saraevskoe field matches well the term "epikarst zone". The understanding of the karst forms formation process in an epikarst zone of the Sokolino-Sarkaevskoe field is presented. Obtained information allows correcting and optimizing the quarry mining planning that improves the quality of the extracted raw material.
