Metallogenesis in Tibetan collisional orogenic belt. I: mineralisation in main collisional orogenic setting.

The main collisional event lasted about 25 Ma from 65 Ma to 41 Ma and resulted in the formation of the main part of the orogenic belt. At least four important ore-forming events occurred during the main collisional orogenic epoch, including the Sn and rare metal event related to crust- derived granite, forming the Tengchong Sn and rare metal ore concentration area in the east Tibetan plateau, the Cu-Au-Mo event related to crust/mantle-derived granite, forming a Cu-Au ore belt 100 km long in south Gangdese, the shear zone Au event, forming the potential Au belt along the Yarlung Zangbo suture zone, and the Cu-Au event related to crust uplift, forming porphyry/epithermal transitional type Cu-Au deposits represented by the Xiongcun deposit.
