摘要 笔者以构造地质调查为主线,以蛇绿构造混杂带建造为基础,通过路线地质调查,剖而测制工作,在全面收集岩石学、岩石化学、年代学、地球化学、运动学等资料的基础上,重点对西金乌兰湖-金沙江蛇绿构造混杂带的物质组成、规模、边界断裂特征等的研究,进而恢复和再造缝合带的发展演化历史。对缝合带的物质组成进行全方位解剖。在综合缝合带组成,结构、构造等方面的基础上对其形成、发展演化进行探讨和研究。为青藏高原及东特提斯超级造山系统的研究提供一定的依据。 The Xijinwulan lake-Jinsha river ophiolite zone is an important plate subduction-collision suture zone that is located in the northern Qinghai-Tibet plateau. The zone extends from the Lazhulong area to Jinsha river via the lake Xijinwulan, Batang area and Derong area. Further to south, it is distributed along the the Ailao mountains and Tengtiao river. So, it is called the Cocoxili-Jinsha river-Ailao mountain ophiolite zone representing an important boundary line between the Songpanganzi terrane and the Qiangtang terrane. The zone is focused as an important tectonic zone by geologists and different opinions existing on its forming age and original spatial distribution. On the basis of previous work of petrology, geochemistry, geochronology, structure geology, this study puts stress on material compositions, scale and boundary faults characteristics of the ophiolite m61ange zone through road geology investigation and certain cross-section measurements, and further recover and reconstruct evolution history of the suture zone. The other purpose for the study is to provide more evidence for formation mechanism of super mountain system of the Qinghai-Tibet plateau and the East Tethys.
