The Qia’erdunbasixi Fe-Cu-Au deposit is located in Sawur on the northem margin of west Junggar in northem Xinjiang.spacerun: yes"> Magnetite and copper are developed mostly along the contact zone between gabbro and diorite. Magnetite mineralization occurs along the inner and outer contact zones of gabbro, assuming typical zoning from magnetite +spacerun: yes"> diopside to magnetite +spacerun: yes"> quartz +spacerun: yes"> andradite + calcite. Wall rock with high Fe seems to be one of the sources for magnetite mineralization. Four stages of copper mineralization could be identified,spacerun: yes"> i. e.,1) albite-quartz; 2) chalcopyrite-pyrite-gold-seriate- quartz; 3) chalcopyrite-pyrite- epidote- prehnite; 4) sphalerite-galena-quartz-calcite.spacerun: yes"> Gold mineralization occurs in pyrite-quartz veins closely related to altered granodiorite-porphyry, which, however, have been locally mylonitized.space prefix = o ns = "urn:schemas-microsoft-com:office:office" />
