The Gremyachinskoye sylvinite field lies in the south of the Volga monocline, to the northeast of the Severo-Kotelnikovskij overthrust. Halogen beds from the field were examined. The study has provided grounds for correlating the field potassium-bearing horizon with the Pogozhskaya rhythmic member from the Volga monocline. The halogen bed formation was influenced by the principal water area of the salt-generating basin in the east and by the calcium chloride brines discharged along the disjunctive dislocations limiting the overthrust zone.
