本文依据地球物理资料,从地球物理的角度论证了把南喜马拉雅地洼区与雅江—喜马拉雅地槽区划分开来之必要性。通过对比研究,给出了这两个构造区的分界线,利用邻国的地球物理资料和研究成果推断了南喜马拉雅地洼区的南运,并大致划分了该区的二级构造区。最后,初步探讨了南喜马拉雅地洼区的深部构造及其演化的力源机制。
Based on the geophysical data, this paper demonstrates the necessity of separating the southern Himalayan depression from the Yajiang-Himalaya terrain based on geophysical evidence. Through the comparative study, the boundary between the two tectonic zones is given. The geophysical data and research results of the neighboring countries are used to deduce the southern transport in the depression area of South Himalayas and divide the secondary tectonic zones in the area roughly. Finally, the mechanism of the deep structure and its source of evolution in the depression area of South Himalayas is discussed.
