| Abstract: | The Qilian and Beishan area is a matching body of many tectonic elements. During the early Paleozoic the Qilian orogenic belt was formed by a accretting of the landmass, include : the palaeocontinent on the northern margin of the Chaidamu Basin, central Qilian and Alax massif. The nucleuses of palaeocontinent of the Beishan area were Mazong-shan central massif as well as the accreted landmass of the southern Mongolia in the early Paleozoic time. The Beishan orogenic belt was formed in the late period of the late Paleozoic time. |
