目前,青藏高原已成为地学界瞩目的地区。自从板块学说提出以后,对于作为大洋-大洋型板块边界的洋脊和大洋-大陆型板块边界的岛弧研究得比较多,论述得也比较清楚,而对于大陆-大陆型板块的边界,则研究得比较少。中国的青藏高原被认为是欧亚和印度两大陆板块碰撞的典型地区,高原的隆起以及巨厚地壳的形成,均和两大陆板块碰撞有关。因此,近年来世界上许多国家的科学工作者对这一地区的研究表示了极大的兴趣。自1980年5 At present, the Qinghai-Tibet Plateau has become the focus of scholars and scholars. Since the theory of the plate was proposed, the island arcs as the boundaries of oceanic-oceanic plates and oceanic-continental plate boundaries have been studied more clearly and clearly. For the continental-continental plate boundaries, however, Fewer. The Qinghai-Tibet Plateau in China is considered as a typical area where two continents of Eurasia and India collide. The uplift of the plateau and the formation of thick crust are related to the collision between the two continental plates. In recent years, therefore, scientists in many countries in the world have expressed great interest in the research in this area. Since 1980 5
