The Qiushuwan copper-molybdenum deposit in the East Qinling molybdenum belt is atypical skarn-porphyry breccia pipe controlled by the porphyry. Ore bodies occur in the biotite granite porphyry, skarn and breccia pipes. According to mineral paragenesis, ore fabrics, wall-rock alteration and intersecting relationship of the veins, the formation of the ore deposit can be divided into three periods. Mineral-forming fluids in quartz, garnet and calcite can be divided into five types, i.e., S-type multi-phase inclusions containing daughter minerals, L-type pure liquid inclusions, C-type three-phase CO2-bearing inclusions, W-type gas-liquid two-phase inclusions, and G type pure gas inclusions. Ore-forming fluid temperature, salinity and redox environment are characterized by regular evolution.
