Origins of ore-forming fluid and material of the quartz–vein type Mo deposits in the East Qinling–Dabie molybdenum belt: A case study of the Qianfanling Mo deposit

The Qianfanling quartz–vein type molybdenum deposit is located in the East Qinling–Dabie Mo belt. The Mo mineralization in the deposit is mainly present as structurally controlled Mo-bearing quartz veins. Based on chromatography analysis of the Qianfanling Mo deposit, the gas compositions of fluid inclusions in quartz dominantly contain H2O and relatively high concentrations of CO2 (11.019 to 18.554 mol%). Cations and anions of liquid...
