Volga-Akhtubinsk flood plain within which there is a researched Volga-Akhtubinsk region divides Astrakhan Anticline into the left-and right-bank parts having various features of a geological structure and development. Astrakhan Anticline is the large tectonic element of the II order of a southwest part of Caspian Depression. In the central part of Astrakhan Anticline, according to KMPV and other geological researches, the depth of the base constitutes 8-12 km. In Volga-Akhtubinsk Entre Rios the code is divided by a deep break (its provision matches the modern bed of the Volga River) into the main right-and left-bank units. In the south the Volga-Akhtubinsk region borders on the Karakul and Smushkovsky zone of raisings, in particular on the Dzhakuyevsky shaft and the Smushkovsky shaft, in the West is limited by the Sarpinsky deflection, in the north - the Zavolzhye deflection. The inundated license area of works is located directly in the central part of Astrakhan Anticline. there corresponds the ledge of the crystal base to Astrakhan Anticline. The socle is blocked powerful (to 12 km) by raznofatsialny thickness of a sedimentary cover.
