On the borders of the upper hydrogeodynamic zone in the Caspian artesian basin

Abstract

This article provides the results from studying the upper part of the section of the entire Caspian artesian basin. The stratification map, the profile section and the isohyps map of the roof of the upper hydrogeodynamic zone were compiled on the basis of generalization of geological and general hydrogeological data. Systematized hydrogeological data on the depositional conditions, structural features and nature of the distribution within the upper hydrogeodynamic zone of the Caspian artesian basin, as well as the supply zones and the areas of transit and discharge of underground waters are provided. The borders of the upper hydrogeodynamic zone of the basin have been drawn as a result.
