众所周如,西藏地区是研究地球深部结构和构造的窗口,是研究大陆板块学说的重要场所,也是寻找热源和其它矿产资源的有利地区.因此,世界各国地学科学家都希望在本地区进行科学研究工作,或与我国科学工作者协作共同探索这一重要地区.中国和法国的地质、地球物理科学家经商讨共同组成“中法喜马拉雅山地质研究队”,对西藏中部广大地区进行地质、地球物理的科学研究工作.深部地震探测是地球物理研究中的重要内容.中法双方共同决定,在中国西藏南部的日喀则地区至北边的那曲地区作地震探测工作.为了探测地壳上地幔的结构,1981年在西藏的南部佩枯错至普莫雍错500公里的喜马拉雅山北麓——雅鲁藏布江地区进行了人工爆炸地震探测工作.本文是中法地质研究队合作的深部地震探测资料的解释结果.
As we all know, the Tibet region is a window for studying the deep structure and structure of the Earth. It is an important place for studying the theory of the continental plate and a favorable area for finding heat sources and other mineral resources. Therefore, geoscientists all over the world want to conduct science in this region Research or collaborate with our scientists to explore this important area.Geoscience and geophysical scientists from China and France have come together to discuss the formation of the “Sino-French Himalayas Geological Research Team” to conduct geological and geophysical surveys in a wide range of areas in central Tibet The deep seismic exploration is an important part of geophysical research.China and France jointly decided to carry out seismic exploration in the Xigaze area to the north of Shigatse area in southern Tibet.To probe the structure of the crust and upper mantle, In the northern Himalayas, 500 km north of Tibet, between Perkar and Puyumavongam, artificial explosions and seismic surveys were conducted in the Brahmaputra area.This paper is the result of deep seismic exploration data co-operated by the Sino-French Geological Research Team.
