The Central Asia Orogenic Belt (CAOB) is one of the world's largest accretionary orogens (Sengör et al., 1993; Xiao and Santosh, 2014). The fifteen most important porphyry Cu (Mo–Au) deposits are distributed in the CAOB (Shen et al., 2010). The West Junggar, as a major component of the core part of the CAOB and Kazakhstan orocline, is located between the Siberian and Tarim plates, and is largely composed of Paleozoic volcanic arcs in the north and accretionary complexes in the south (Yang et al., 2012, 2013). Gold and copper mineralization is well developed in volcanic rocks and intrusions of the West Junggar. There are the Baogutu Cu–Au, Hatu Au, Tuketuke Cu, Hongyuan Cu–Mo and Hongshan Cu deposits. Since the discovery of the this deposits, many studies have been addressed including geology, geochemistry, geochronology, alteration, mineralization, stable isotopes and fluid inclusions. However, the geodynamic settings and tectonic model of porphyry copper–gold deposits from this region were not given much attention.
