1987年6月,通过课题论证,同行专家评审,“滇川西部特提斯带岩石圈构造演化”课题正式列入“七五”期间重大项目。我们之所以选择滇川地区,因为它是世界上规模最大的喜马拉雅一阿尔卑斯造山带的一部分。它横贯欧亚大陆,是古老的特提斯海(洋)消亡的产物,它记录了两大古陆块会聚碰撞的过程。尤其是滇川西部,是印度大陆与欧亚大陆在45百万年以前碰撞,引起近东西向青藏高原的隆起,而到滇川西部骤然拐弯成近南北走向的横断山脉,这种地理上和
In June 1987, the project entitled “Evolution of Tectonic Belt in the Tethys Belt of the Western Yunnan Drought” was formally included in major projects during the “Seventh Five-Year Plan” through project demonstration and peer review by experts. We chose the Yunnan region because it is part of the largest Himalayas-Alps orogen in the world. It traverses the Eurasian continent and is the product of the demise of the ancient Tethys Sea, which documents the convergent collision of two ancient land masses. Especially in the western part of Yunnan-Sichuan region, the collision between the continent of India and Eurasia over 45 million years ago resulted in the uplift of the nearly east-west Qinghai-Tibet Plateau and the sudden turning into a nearly north-south transverse Hengduan Mountains in western Yunnan,
