摘要
The orogenic process of Tianjingshan was reproduced based on seismic,drilling,field survey data and equilibrium profile method.The evolution of Tianjingshan Region can be divided into extension basin(Sinian-Late Middle Triassic),continental emergence extension evolution stage(Late Triassic-Late Middle Jurassic),lifting and denudation stage(Late Jurassic-Early Cretaceous) and reformation succession stage(Late Cretaceous-present).Through structural physical simulation experiment,it is preliminarily confirmed that the thin-skinned structure developed during the Indo-Chinese epoch was formed by the combined action of the southnorth extrusion stress and northwest-southeast gravity gliding;that during the Himalaya period,Tianjingshan Region was deformed into imbricate thrust structural combination;that the Tianjingshan structure has multiple decollement layers,which form incoordinated structural deformation with layered deformation and vertical superposition.
