    Abstract:

    The India/Asia convergence-collision processes underwent Neo-Tethysian oceanic expend, subduction and acrecetion at the southern Asia continent , as well as formation of the Gangdis magmetic belt, the Yaluzangbu suture, the Himalaya collision-orogenic belt and the lateral extrusion terrains of the west Yunnan caused by large-scale material escaped to SE of the Tibet plateau. The Gangdese, Yaluzangbu, Tethys-Himalaya and West Yunnan metallogenic belts located at southern and southeastern parts of the Tibet plateau have important prospecting breakthrough. Through studies for tectonic positioning of four metallogenic belts and scientific issues related to the resources prospects, we propose that the island arc-type porphyry copper / gold mine in the Gangdese metallogenic belt has significant potential prospecting, attention to the study for the eastern Tibet - western Yunnan subduction/ collision type magmatic metallogenic specialization. We need to expand the Luobusha chromite ore district development scale, as well as find a new chromite vision area of large ultramafic massifs in the Ali region. In superimposed deposits of multi-stage mineralization in the western Yunnan, we focus on Paleo-Tethys and Neo-Tethyan metallogenic types, as well as mineralizations related to strike-slip shear zone constrained by oblique collision mechanism. To determine the relationships between the Tethyan -Himalayan mineralized zone and the Southern Tibet detachment (STD) and attention to the Eocene- Miocene metallogenic specialization of high Sr / Y granite (porphyry) type and prospecting
