英文摘要	The Kalaxianger porphyry Cu ore belt in northern Xinjiang is situated on the northeastern margin of the Junggar Block, which tectonically formed in the middle part of the Central Asian Orogenic Belt. Most of the deposits in the copper ore belt underwent tectonic deformation, especially the Yuleken porphyry Cu-Mo deposit. The ore-bearing intrusive rocks in the deposit are composed of granite porphyry, granodiorite porphyry and monzogranite porphyry, which intrude into intermediate-mafic volcanic and volcanic-sedimentary rocks of the Middle Devonian and Early Carboniferous. Mylonitic deformation is common in both the ore-bearing porphyries and the wall rocks, resulting in Cu-Mo mineralisation filled along the schistosity, or along cleavage and in the chalcopyrite-K-feldspar-quartz veins. According to the previous works, the tectonic evolution and mineralization process in the Kalaxianger porphyry Copper ore belt were summed up as following. Two period of medium-acidic porphyries were intruded in an island arc setting related to oceanic subduction in the Middle-Late Devonian and accompanied by large-scale Cu-Mo mineralization; then the ore belt went deformed, relocated and enriched for copper in the NW ductile shear zone in Early Carboniferous; With the formation of Hadanxun and Mayinebo A-type granites, the superimposed Cu mineralization occurred in the post-collisional stage in Late Carboniferous-Permian; In Mesozoic, another important superimposed mineralization was characterized by hydrothermal Cu ore veins.
