Basin assemblages and tectonic evolution in the Bohai Gulf and its neighbors

According to multi-disciplinary research advances in recent years, three blocks which named Jiaoliao-Bohai block, central North China block and Ordos block are divided.The differences of the tectonic association, types, styles and features in the space, and ewlution fmm Archaean to Cenozoic in the time, between the former two blocks are discussed.Tectonic features and evolution in the four tectonic stages of Precambrian, Indo-China, Yanshanian and Cenozoic are emphasized especially here.All of them described above have inherit and neogenic property.The temporal-spatial change and interaction among basin assemblages in the above four stagers are analyzed.Escape tectonic model is employed to interpret coeval compressive and extensional basins in the study area.
