| Effects of the Tethyan Oceanic Crust on the Qinghai-Tibet Uplift |
| Mantle convection made the Tethyan oceanic crust display an entirety and rigidity, and caused it to plunge in a “drawer style” beneath the Qinghai-Tibet continental crust. As a result, the first uplift event occurred. The Tethyan oceanic crust mentioned above underwent intensive folding, fracturing and overprinting because of impediment caused by the rigid massifs in the Sichuan,Ordos and Qaidam basins. These resulted in not only the second folding, fracturing and uplifting of the Qinghai-Tibet continental crust, but also subsidence, folding and fracturing of the Moho. Therefore the geological and geographical features of the present Qinghai-Tibet plateau were formed. |
