Abstract

Earlier investigations have shown that most sedimentary basins on continental crust were formed without significant extension. These basins are of two main types. Cratonic sedimentary basins, 3 to 15 km deep, form as a result of slow compensated subsidence at a rate of 10 to 100 m/m.y. over a long period of time (300-1000 m.y.). Miogeosynclines usually form by rapid uncompensated subsidence at a rate of 0.2-1 km/m.y., in a short period of time (1-10 m.y.). In this paper, the authors examine the evolution and distribution of hydrocarbon deposits in the oil and gas basins of the Persian Gulf, which contain more than 60% of the oil and 40% of the gas reserves of non-Soviet countries. They conclude that the oil and gas basins of the Persian Gulf were formed by repeated rapid subsidence without crustal extension. The rapidity of the subsidence was responsible for high heat flow, intensive local tectonics, and the deposition of suitable source beds, reservoir rocks and caprocks, factors that are responsible for the immense oil and gas resources. 44 references, 2 figures.
