On scientific approach toward formation of Productive Series on the Southern coast of The Caspian Sea

T.Y. Baharov

There is common approach on formation of Productive Series of Pliocene in Southern Caspian depression that is mainly related with Paleovolga taking into account the rivers, running into Caspian basin. But there are some problems, waiting to be solved in this approach: Formation of large-volume sediments during short time, spreading rude grainy, mainly sandy sediments along width of The Caspian Sea, depression of basin bottom toward great depth, lack of biofacies and etc. These problems are solved in the new approach proposed. Speed and huge-sized volume play an important role in the interpretation of this process. It means that study of approaching systematically to the geological development (platform- deep aqueous depression and the zone separating them, it means Northern, Southern and middle Caspian) of the region, taking into account isostasy law is based on morphostructural, paleogeographical, paleotectonic and sequence-stratigraphic researches. As a result of systematic approaches and integration of those directions and study of genetic relation between them and dynamics, the reasons of high speed Northern and middle Caspian waters flow getting over the border (Cordilleras mountain, hills formed in the result of gathering sediments), containing of isolation height are defined and grounded. Thus, gathering sediments of Productive Series in Southern Caspian basin is related with natural calamity geological incident, happened at the beginning of Pliocene.
