Oil and gas bearing provinces of South Caspian downwarping zone and Persian Gulf – reliquiaes of Paleotethys continental borderland

The studied region belongs to active seism geodynamic zone and the movement and migration directions of hydrocarbon are connected with multidirectional faults. The oil and gas bearing provinces of Persian Gulf and South Caspian are the elements of integrated geodynamic block, and they are obviously illustrated with modern seism geodynamic map and regional physiographic model. Rich oil and gas bearing belts-Zagros system is located in Persian Gulf northern, and Absheron-Pribalkhan zone in South Caspian northern parts. In order to clear up that this is a coincidence or connected with the geological evolution of the region, geological-geophysical materials have been analyzed. It is supposed, that the hydrocarbon potential of Persian Gulf and South Caspian is connected with passive continental borderland of Paleotethys. Zagros system in Persian Gulf and fore-Caucasian-Turkmenian deepseated fault in South Caspian are the ways of migration and generation of hydrocarbons.
