河套盆地晚侏罗世逆冲构造及其油气地质意义
Late Jurassic thrusting in the Hetao Basin and its petroleum geological significance
摘要
Abstract
The Hetao Basin,located on the northwestern margin of the North China Craton,is a Cenozoic rift basin developed on cratonic basement.Based on drilling and seismic profile data,this study systematically compares and analyzes the basement structural characteristics of the Hetao Basin and the Ordos Basin.The results reveal that north of the Yellow River fault,the Lower Cretaceous to Cenozoic strata in the Hetao Basin unconformably overlie the Archean metamorphic basement,while south of the fault,the Ordos Basin preserves a complete succession of typical North China Craton cover sequences from the Changcheng System to the Cretaceous.Seismic profile analysis indicates that the Yellow River fault experienced south-directed thrusting during the Late Jurassic,leading to uplift and extensive erosion of the hanging wall rocks north of the fault,which resulted in the exhumation of the Archean basement to the surface.The widespread Late Jurassic thrust faulting along the northern margin of the North China Craton is likely associated with the closure of the Mongol-Okhotsk Ocean and subsequent continental collision events.关键词
