Abstract
The basin of Bohai Bay is formed by numerous large and small blocks of the earth’s crust submerged to different depths along large faults. Depressions occur along submerged limbs of the largest blocks, which are depocenters of sediment accumulation, mainly for deep water sediments. Eighty depressions are located in this territory, which measures 200000 km2, and the Dongying Depression is one of the largest among them. During the Cenozoic age, the amplitude of submersion within the limits of this depression reached 6–9 km. Numerous deposits of oil and gas have been found in the sediments formed during this period, which are mainly gritstones, sandstones, clays, and pyroshales.
