%X High salinity fluid inclusions containing daughter minerals have been found in quartz and ankerite of main mineralizing stages, Taibai and Baguamiao gold deposits of Shaanxi province, located in South Qinling. Both deposits occur in Devonian low grade metamorphic rocks. Daughter minerals were detected as pyrite, ankerite, halite and arsenopyrite by SEM/EDS and EPMA. It is concluded that ore forming fluid was formed under complex physico chemical conditions. According to the tectonic setting, mineral association of main mineralizing stages, high PGE content in hydrothermal sulfides, Chondrite normalized REE pattern of carbonate cement from Taibai gold deposit, carbon isotope characteristics, it is believed that ore forming fluid has a deep (mantle) source.
