Subsidence History of the Bohaiwan Basin and Implication for Cenozoic Dynamic Processes in Eastern China

摘要：

The Bohalwan basin belongs to a family of extensional basins in East China. The Cenozoic subsidence of the basin is controlled by a combination of lithospheric thinning and polycyclic strike-slip movements. Three episodic riftings have been identified, the Paleocence-Early Eocene, Middle-Late Eocene and Oligocene rifting. Similar to a general extension basin, the basin underwent rifting and post-rifting stages. However, superimposed dextral movement of strike-slip fault resulted in intensified subsidence or local inversion during the Oligocene and Late Miocene-Quaternary in the Bozhong depression. The results indicate that there is a close relationship between formation and evolution of the Bohaiwan basin and lithospheric thinning.
