Depositional history of Pliocene Productive Series in the South Caspian basin and its supsidence
N. AbdullayevProductive Series in the South Caspian basin is interpreted as a stratigraphic sequence created by the base level fall about 1.5 km during the Messinian. This rapid fall of the base level caused canyon erosion of the Paleo-Volga and integration of the river drainage towards the South Caspian basin. The Productive Series sediments where thus deposited in the topographic depression, where base base level changes were defined not by global eustatic but by local climatic or tectonic factors. Two river basins were contributed most to the sediment volume in the Caspian-Paleo-Volga and Paleo-Amudarya. Volumes of sediments accumulated during the deposition of the Productive Series can imply a large-scale denudation of the basin margins during relatively short period of time.
