Abstract: Abstract：Porphyry copper deposits in the world are confined mainly to the Mesozoic-Cenozoic circum-Pacific belt and Paleo-Tethys belt and Paleozoic Central Asia-Mongolian belt, where convergent plates are developed. Tibet is one of the best developed regions of convergent plates in the world, in which the Jinshajiang, Yarlung Zangbo and Nujiang-Bangong Co suture zones lie. These suture zones have a long history of oceanic plate subduction and continent-continent collision with well-developed tectonomagmatic activity marked by widespread plutonic and high-level granite-porphyry, which is favorable to the formation of porphyry copper (-gold) deposits and other related deposits. By referring to the experiences in assessment of porphyry copper deposits at home and abroad in recent years, this paper looks forward to the prospects of porphyry copper deposits in Tibet.
