西藏羌塘盆地是特提斯构造域内晚古生代—中生代海相复合盆地。经历了晚古生代板块构造演化阶段、中生代板块构造演化阶段和新生代抬升剥蚀阶段 ,形成了晚古生代大陆边缘盆地、中生代南羌塘被动大陆边缘和北羌塘弧后盆地以及晚侏罗世之后的构造地貌盆地。受多期构造运动作用 ,盆地从北向南形成了北缘冲褶带、北羌塘变形带、中央碰撞隆起带、南羌塘变形带和南缘冲断带五个构造单元。变形由坳陷边缘到中心逐渐减弱 ,侏罗山式褶皱样式 ,反映出盖层浅层滑脱的变形特征
The Qiangtang Basin in Tibet is a Late Paleozoic-Mesozoic marine composite basin within the Tethys tectonics. After the late Paleozoic tectonic evolution stage, the Mesozoic tectonic evolution stage and the Cenozoic uplift and erosion stage, the Late Paleozoic continental margin basin formed. The Mesozoic southern Qiangtang continental margin, the northern Qiangtang backarc basin and the Late Jurassic Geomorphology basins. Due to the multi-tectonic movement, the basin consists of five tectonic units in the north margin, the kerogen belt, the northern Qiangtang deformation belt, the central collision uplift belt, the southern Qiangtang deformation belt and the southern margin thrust belt. Deformation from the edge of the depression to the center gradually weakened, Jurassic fold pattern, reflecting the deformation of the shallow cover slip deformation
