摘要
In the West Kunlun Mountains there exists a Caledonian tectonic zone. The fifth suture zone of the Qinghai-Xizang Plateau was formed as a result of closing of the proto-Tethys Sea caused by the Caledonian movement. The discovery of the Sinian- Cambrian Wanbaogou Group and the Middle Ordovician-Silurian Halagel Group around the Golmud area in East Kunlun, the discovery of the early Paleozoic rockbodies at Wanbaogou and Huxiaoqing, and the unconformity between the Devonian molasse and the underlying strata provide evidence for the existence of the Caledonian tectonic zone. There are not only similarities, but also significant differences between the East Kunlun and West Kunlun.
