Hydrogeological and geotectonic features of the post-salt Upper Paleozoic-Mesozoic-Cenozoic paleobasins of the pre-Caspian salt dome region

The article describes the regularities of formation and distribution of groundwater and brines in the post-salt layers of the Caspian hydrogeological megabasin. Author investigated the qualitative composition of underground brine of sedimentary cover water of the post-salt complex. The results of analysis and typification of the mineralization and ionic composition of saline waters are presented. The basic geochemical and genetic types of brines were characterized. Vertical zonation of ionic saline composition with a depth was identified. The author demonstrate a possibility of complex use of brines and waters of the post-salt strata.
