| STRUCTURAL ＦEATURES AND TENTATIVE DIVISION OF THE TERRANES IN QINGHANG-XIZANG PLATEAU |
| The Qinghai-Xizang plateau may be divided into five terranes, i.e. Hinalaya terrane, Gangdise terrane, Qiangtang terrane, Bayankala Terrane and Kunlun terrine, each of these terranes has its own characteristic structural features and has been seperated from one another by ocean basins. The time at which the ocean basins closed and folded to form confinent is younger from north to south. The oldest ocean basin was formed in Devonian. All the basins closed by the end of late Cretatieus. They experienced two cycles of opening and closure during their evolution history.The first cycle was from Devonian to Permian and the second was from Triassic to the end of late Cretaceous. Before closure, the southern and northern terranes were mostly in a neritic facies environment. After closure the northern terrane uplifted, and formed new continent, whereas the southern terrine mostly remained in a neritic facies environment. The northern boundary of the Gondwana land is the Jinshajiang river fracture zone and the Gondwana land broke into a serial terranes from Triassic period. |
