The study destination of intracontinent orogen and metallogenesis in Himalayan epoch of the large composite basin, East Tibet is to establish the tectonic model and the diagenesis-metallogenesis model on Hengduanshan type Intracontinent collision orogen. It is proved that the cover folding nappe would be in the early Himalayan epoch by the research of the stratum contact relation, the tectonic deforming characteristic and the ore control factor. The main diagenism, metallogenic spaces are the trap of the nappe structure, of the strike-slip structure, of the strike-slip nappe brittle-ductile shear belt and of the cross structure orthogonal with the strike of the orogenic belt. According to the study of the intracontinent orogen dynamics and metallogenesis in Himalayan epoch, this paper has established the tectonic model of Hengduanshan type intracontinent orogen and the diagenism-metallogenesis model of the large composite basin in eastern Tibet. There is the fact that the metallogenesis of the porphyry copper deposit was in the tectonic change period from the peak of the early Himalayan movement to the mid-Himalayan movement. And, the Pb-Zn (Ag ) mineralization in the hrust nappe trap was resulted from the late Himalayan movement.
