Tectonic Evolution of the Zhuanghai Area, Bohai Bay Basin, East China:  Application of Balanced Cross Sections
详细信息   
摘要

In this paper, the authors selected two seismic profiles and compiled two structural growth sections in the Zhuanghai area of the Jiyang sag. The whole area suffered from compression and uplifting during the Triassic-Middle Jurassic phase because of intense extrusion stress related to the Indosinian movement. During the late Jurassic and early Cretaceous, intense extension occurred in East China, and the whole area rifted, leading to the huge thickness of sedimentary sequence. In the Late Cretaceous, the area suffered from uplift and compression associated with the sinistral strike slip of the Tanlu fault. In the Palaeogene, a rifting basin developed in the area. Finally, it became stable and was placed in its present position by dextral strike-slip motion since Neogene.
