| Tectonic Evolution of the Southern Region in the Middle Gangdese Batholith, Southern Tibet |
| The Gangdese magmatic belt, located in southern margin of the Lhasa terrane, was related to the Neo-Tethys oceanic evolution and Asian-Indian colli-sion. Therefore, the Gangdese magmatic belt is a still research focus of the Tibetan geosciences. However, some basic and essential issues have been under dis-cussion and debated, such as the Triassic–Jurassic evolutionary characteristics or nature of the Neo-Tethys oceanic crust, formation ages and dy-namic mechanisms of ductile shear zones and denuda-tion and uplift models of the Gangdese batholith in southern Tibet. These issues cloud the understanding and tectonic framework of the Tibetan plateau and the Neo-Tethys oceanic evolution, especially in assessing accurately ore deposits and met-allogenic belt for the whole Gangdese magmatic belt. |
