During the formation of the Caspian lowlands, favorable conditions for karst repeatedly created on its territory. Nowadays karst rocks outcrop on disparate local territories. They are confined to bare caprocks of salt domes. The article describes the brief history of karst studies near lake Baskunchak area located in the northern part of Astrakhan region at Achtubinskiy administrative region. Also describes variety of surface and underground karst landforms. The basic regularities and features of Pribaskunchakskiy karst area development subjected to geotectonic structure of the territory. Modern karst processes around Lake Baskunchak proceed about 40 thousand years after early khvalynskiy transgression of the Caspian Sea. Karst area terrain is unstable and characterized by high activity. Noticeable influence on the development of karst topography and surface activation of karst and karst-suffusion processes in the study area have anthropogenic and technogenic factors. The further systematic, comprehensive survey of karst in the study area, as well as conducting of long-term geodynamic monitoring must be research.
