Evolutional Impacts of Extensional Linkage Fault System in Dongpu Sag
Dongpu sag NNE main basement fault extending with increasing depth intersects the deeper decoupling detachment fault and connects to the induced transfer faults in various manners, constituting the extensional linkage fault system in Dongpu sag. Linkage fault system in different sections of Dongpu sag is characterized by diverse geometrical and kinematical features. The evolution of extensional linkage fault system in Dongpu sag can be roughly divided into four periods and evolutional styles, which exert significant impacts on Paleogene sedimentary and petroleum geological conditions.
