喜马拉雅和相邻的西藏高原，构成了地球上最大的高原和异常厚地壳的地区，是作为印度板块和亚洲板块新生代碰撞的结果，并被认作是典型的陆－陆碰撞［１．２．３．］地带。在此，我们报道了用深地震反射剖面方法进行本区地壳成像的第一个结果，试验的１００ｋｍ长剖面，布置在特提斯喜马拉雅（ＴｅｔｈｙａｎＨｉｍａｌａｙａ）最南端，且跨过了喜马拉雅山脊，接近高喜马拉雅（ＨｉｇｈＨｉｍａｌａｙａ）地带，剖面显示了在地壳中部有一强反射带。它可能代表了一个活动的道冲断裂，印度板块是沿此断裂俯冲到藏南之下；上地壳反射使人们联想到上地壳存在着大规模的叠瓦状结构；莫霍反射来自本区双倍正常地壳厚度的巨厚地壳的底部。这些结果对西藏南端地壳增厚，是由于印度大陆地壳整体俯冲到包括特提斯喜马拉雅地区地壳之下的观点，给予了实质性的支持。
The Himalayas and the adjacent Tibetan plateau, which form the largest plateau and unusually thick crust in the Earth, are the result of the Cenozoic collision between the Indian and Asian plates and are considered typical land-continental collisions [1.2 .3. ]zone. Here we report the first result of a deep seismic reflection profiling method for crustal imaging in this area. The 100 km long section of the experiment was placed at the southernmost tip of Tethyan Himalaya and crossed the Himalayan ridge, approaching high HighHimalaya Zone, section shows a strong reflection in the middle of the crust. It may represent an active Tao Chong fault along the fault plate below the Indian subcontinent to the south of Tibet. The upper crustal reflections remind us that there is a large shingle-like structure in the upper crust. Moho reflections originate from the double The thickness of the normal crust thick crust bottom. These results thickened the crust in the southern tip of Tibet due to the substantial support of the Indian mainland as a whole due to the subduction of the crust to include the crust below the Tethyan Himalayas.
