Features of Postsedimentation Alteration Sand Accessory Mineralization with in Rocks at Final Stages of Halogenesis in the Outer Slope Zone of the Caspian Depression

The paper deals with regularities of postsedimentation changes in rocks at the halogenesis final stages within the Gremyachinskoye potassium salt field. Relation ship has been revealed among the postsedimentation processes, brine composition peculiarities, structure and regularities of terrigenous material inflow. Substanti al role of partial metasomatic replace mentofsalting-out halite in carnallite rocks is specified, as well as the role of diagenetic processes in halogen series, frequently accompanied with initial phases of plicative deformations.
