摘      要：Evidence from such diverse fields as geology,seismology and geophysic exploration indicate that the backarc spndingandterrane matching models can not be reasonably used to explain the evolutionary feature of the East China Sea (ECS) Basin. A new model,the persistent extending-pulsative compressing (PEPC) model,is proposed by the authors. An active persistently extension oceanward took place at the margin of the continental lithosphere,because of its inhomogeneous composition,texture and thermal state, and was conttolled by deep-seated (mantle) geological *** extension is the main cause for the formation and evolution of the ECS *** northwestward movement of the Philippine Sea lithosphete provides the basin with a *** compression is short in time but powerful in force strength, i. e. in a pulsative form, relatively to the above-mentioned extension. The PEPC model plays a new role in comprehencing the laws of hydtocarbon accumulation and prospecting for oil /Ras fields in the ECS *** are several source- reservoir-caprock associations related closely to the multiperiodic persistent extending-pulsative *** Paleocene and Eocene are the main mature source rocks and the Oligocene to Miocene are the potential source rocks in the Shelf *** the persistent extension is favourable to the formation of the hydrocarbon areas, but the pulsative compression causes them to be destroyed.
