博格达山北缘前陆褶皱冲断带构造特征及其动力学意义
The structural characteristics along the northern piedmont of Bogedashan and its dynamic significances
摘要
Abstract
The fold-and-thrust belt of the northern piedmont along Bogdashan is a hot spot of modern geological study. The most previous studies focused on the Paleozoic and Cenozoic structural deformations. However, few studies concerned its Mesozoic multi-phases deformations. This study distinguished three phase of deformation since Mesozoic along the northern piedmont of the Bogdashan, based on carefully structural observation in field, image satellite and previous published seismic profiles. The first one is the Cenozoic thrust structure and related folds,which is caused by the far-effect of the India-Eurasia collision. The second deformation is characterized by the wide wave-length folds during the boundary between the Late Jurassic and the Early Cretaceous. The third deformational phase probably related to the inception of the uplifting of Bogdashan. It shows intensive deformation within the Upper Permian. These results suggest that Bogdashan has the characteristics of multi-phase uplifting, mainly caused by the collisions of different small blocks at the southern edge of Asia.关键词
