Based on field investigation of large number of ore deposits including some latest discoveries and multidiscipline comprehensive research,we demonstrated the general features of metallic deposits and we suggest that Paleozoic archipelago -type collisional orogen at North Xinjiang,northwestern china show intimate similarity with the metallogenesis of Southeast Asia Cenozoic *** briefly described the characteristics of major porphyry-type,skarn-type Cu deposits and typical high-sulfidation type(HS-type) and low-sulfidation type(LS-type) epithermal Au deposits as well as some latest *** isotopic age-dating on the Tuwu-Yandong superlarge porphyry Cu deposits revealed that they formed in Late Devonian to Early Carboniferous in an accretionary arc *** tectonic settings of epithermal Au deposits and its linkage with porphyry Cu deposits are further *** formation condition for porphyry Cu deposits is more strict than epithermal Au *** distribution width for porphyry Cu deposits in the orogenle belts is more limited than epithermal Au *** discovery and prospecting progress of the Kalatage HS-typc Cu-Au deposit were *** significance in further exploration was suggested.
