【摘要】 青藏高原内由北向南主要发育有 4条巨型断裂构造带 :南昆仑断裂构造带、龙木错—金沙江断裂构造带、班公湖—怒江断裂构造带和雅鲁藏布江断裂构造带 ,以之为界 ,可以把青藏高原划分为昆仑块体、巴颜喀拉块体、羌塘—昌都块体、冈底斯块体、喜马拉雅块体。各块体内发育了多个中新生代“残留盆地”,它们大多为“叠合盆地”。根据青藏高原内的构造演化和沉积地层的发育特征 ,结合板块构造理论 ,可把青藏高原划分为 2 7个中新生代“残留盆地”,依其原型盆地性质可把其归纳为板内裂陷、被动陆缘、弧间和弧前等 4种成因类型。更多还原

【Abstract】 There exist four large fault belts in the Qinghai Tibet Plateau from the north to the south.They are the southern Kunlun belt, the Longmucuo Jingshajiang belt, the Bengongcuo Nujiang belt and the Yaluzangbu belt.According to these block boundaries, the plateau can be divided into six terraces including Lunlun, Bayankala, Qiangtang Changdu, Gangdes and Himalaya.In each of the terranes there are many Mesozoic Cenozoic remained basins which are overlapping basins.Based on the characteristics of the tectonic evolution and the sedimentary layers of the plateau, and referencing the plate tectonics theory, the plateau can be divided into twenty seven Mesozoic Cenozoic remained basins.Based on their proto types all of the basins can be classified into five categories which are interior rift basin, passive continental margin basin, fore arc basin, inter arc basin and back arc basin.更多还原
