摘要
The North China Craton can be divided into the Western and Eastern Blocks separated by the Trans-North China Orogen.Since the Mesozoic,the North China Craton underwent thinning and destruction.The destruction center is located in the Eastern Block,whereas the Western Block and the north-trending Trans-North China Orogen remained their integrity,and the transition zone between them is the eastern Taihang Mountains.Two subparallel important faults developed in the Taihang Mountain region,called the Taihang Mountain Large Fault and the Eastern Taihang Mountain Fault respectively,as the major faults of the Eastern Taihang Mountain Fault Belt.Previous studies revealed that the Eastern Taihang Mountain Fault is inherited from Precambrian tectonic belts controlling the differences of Precambrian crystalline basements between the Eastern Block and the Taihang Mountain Region.Since the Palaeocene,the Eastern Taihang Mountain Fault developed into negative morphotectonic inversion as a normal fault in the western margin of the Bohai Bay Basin.However,the Taihang Mountain Large Fault existed in the Yanshanian as a major thrust,and played an important role in the uplift of the Taihang Mountains.During the middle Miocene,along with the formation of the Shanxi graben system,the Taihang Mountain Large Fault underwent a negative structural inversion and controlled the development of a series of intermontane grabens.Since the Cenozoic,the tectonic migration in this region as a whole jumped toward the west,developing under regional strike-slipping and extension a new intraplate mountain-basin relationship.
