东秦岭-大别造山带中新生代盆地构造特征与形成机制
Mechanics and evolution of Mesozoic and Cenozoic basins in the East Qinling-Dabie Orogenic Belt
摘要
Abstract
In the East Qinling-Dabie Orogenic Belt, the Mesozoic and Cenozoic basins controlled by the Mesozoic and Cenozoic stretching and strike-slip faults formed a complete stretching and detachment system together with metamorphic core complexes in Dabie area. These basins have experienced two evolution stages including orogenic extrusion and regional extension in response to the NWW and NE oriented basement faults, the changes of basin subsidence direction, and the time-space relationship of foreland basins to the north of the orogenic belt, which is in accordance with the evolution history of the East Qinling-Dabie Orogenic Belt. The geophysical characteristics of deep formations in the orogenic belt and the generation of granite complex during the late stage of orogenic movement showed that the basins in the orogenic belt were controlled by regional extension and deep adjustment. The basins were formed due to the subduction and relaxation of the East Qinling-Dabie Orogenic Belt and regional extension.关键词
