The metallogenic ages of porphyry-epithermal deposits in northern Xinjiang are systemically summarized in this paper. Based on tectonic setting, the ore deposits can be classified into three types, i.e., ocean-continent subduction, collision origin composed of collision sub-type and post-collision sub-type, and intra-continent. Porphyry deposits in different metallogenic epochs show genetic and regional “isospatial metallogenesis” characteristics and zoned distribution. From early to late the deposits expanded gradually from the position close to the suture belt outwards, and from linear distribution to planar distribution.
