Characteristics of caves in the Inder karst district
The article gives a brief description of the karst area located near the Lake Inder (Atyrau region, Kazakhstan) and describes 14 caves found and surveyed during research expeditions organized by members of the section of speleology and karst studies of the Astrakhan branch of the Russian Geographical Society. Sulphate karst in this region is due to the emergence of ancient sedimentary rocks of the late Paleozoic age, raised on the day surface due to salt tectogenesis and forming the upper part of the keprok of the salt-dome massif. Inder karst region has a weak speleological study and is perspective for the further researches.
