Abstract:
Based on measures of fluid inclusion in different levels and mineralized belt, the characteristics and evolution process of ore-forming fluids in the Qibaoshan Cu-polymetal deposit are discussed systematically. Decrepitation thermomer of pyrite shows temperature of the ore-forming fluids dropped slowly from 291℃ to 279℃ around the rock body in horizontal, and varied from 312℃ to 228℃ from the lower level upward in profile. The main composition of the fluids was H2O and CO2, the concentrations of H+ decrease during evolution of the ore-forming fluids, showing tendency of the fluids from acidity to alkalescence and process of ore-forming.
