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

摘要

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 evolution from Archaean to Ceno- zoic 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 stages are analyzed. Escape tectonic model is em- ployed to interpret coeval compressive and extensional basins in the study area.
