The Qiangsheng gold deposit belongs to quartz vein type. The fluid inclusions consist of four types:aqueous single-phase inclusions,aqueous two-phase inclusions,carbonated two-phase inclusions and carbonated three-phase inclusions. The fluid inclusions are characterized by low salinity( 5%-9% Na Cl eqv),low density( 0. 66--0. 72 g / cm~3) and medium temperature( 210℃--250℃). The pressure of ore-forming is 60--95 MPa and the metallogenic depth is about 5. 49--7. 56 km. During the mineralizing process,ore-forming fluid underwent fluid unmixing in CO_2-H_2O-Na Cl system. The stable isotope results indicate that the ore-forming fluids mainly generated from mantle,with the participation of a small amount of atmospheric water. Comprehensive studies have suggested that Qiangsheng gold deposit belongs to the type of mesothermal hydrotherm with mantlederived fluid participating in mineralization.
