青藏高原的地质构造一向为国内外学者所瞩目。近年,中国科学院和地质矿产部都曾组织了较系统的调查研究和学术讨论。阿里地区和札达盆地以南的边境地带,交通条件困难,取得的资料尤为可贵。现在阿里地区的科学研究成果正在陆续发表,本文仅对西藏的构造轮廓作一简单回顾,以待将来验证。 50年代前期,作者有幸接触西藏的化石资料,初步认为雅鲁藏布江以北可能是一个前寒武纪地块(1956)。70年代中,申札地区稳定型下古生界的发现及其与念青唐古拉变质岩群关系的推定,至少说明冈底斯地块形成于前寒武纪。国外学者较早地指出了雅鲁藏布超基性岩带的意义,并认为它是大陆板块碰撞的典型。自常承法 以板块叠加的概念对青藏
The geological structure of the Qinghai-Tibet Plateau has always been the focus of scholars both at home and abroad. In recent years, the Chinese Academy of Sciences and the Ministry of Geology and Mineral Resources have organized more systematic investigations and academic discussions. The border areas to the south of the Ali area and the Zanda basin have difficult traffic conditions and the information obtained is particularly valuable. Now the scientific research achievements in Ali area are being published one after another. This article only briefly reviews the structural contours of Tibet for future verification. In the early 1950s, the author was fortunate to have access to fossil data in Tibet, initially suggesting that the Precambrian block might be north of the Brahmaputra (1956). In the 1970s, the discovery of the stable Lower Paleozoic in the Shenzha area and its relationship with the Nyainqentanglha metamorphic group suggest that at least the Gangdise massif was formed in the Precambrian. Foreign scholars earlier pointed out the significance of the Brahmaputra ultrabasic rock belt and considered it to be typical of continental plate collision. Since the law by the plate superimposed on the concept of Qinghai-Tibet
