西昆仑山前柯东构造带变形特征、机制及物理模拟
Structural deformation characteristics, mechanics and physical modeling of Kedong structure in piedmont of western Kunlun Mountain
摘要
Abstract
The Kedong structure locates in the front of the western Kunlun orogenic belt and was impacted signi-ficantly by the uplift of the western Kunlun Mountain. Deformations took place mainly in Neogene and Quaterna-ry. Seismic data showed that the deformations in deep series were featured by thrust and imbricate faults, while in the shallow series a set of Cenozoic monoclines inclined to the north developed. The structural deformation process and mechanism of the Kedong structure were analyzed with physical simulation. It was concluded that the Kedong structure was mainly controlled by compression from south to north, erosion and synkinematic sedimenta-tion. Paleogene evaporate bed and Jurassic coal-series stratum worked as regional composite detachment and con-trolled the decoupling and differential evolution of the upper and lower structures.关键词
