Title: Tectonic Features of Oil and Gas Basins of Eastern China: ABSTRACT

Author(s): Tang Zhi

Article Type: Meeting abstract

Abstract:

Petroleum exploration in eastern China in recent years indicates compressive folding as the main tectonic feature during the Mesozoic. In the Cenozoic, tensile block-faulting formed a new stage of development. This "compression followed by tension" stress field created two different sedimentary, tectonic, and oil-occurrence cycles, two different kinds of oil and gas basins, and two different modes of oil and gas accumulation.

In the "depression-type" sedimentary basins of the Mesozoic, oil and gas accumulations are mainly controlled by anticlinal structures of the second order. In contrast, in the "fault-depression-type" Cenozoic sedimentary basins, oil and gas occur in traps formed by block faulting.
