δ18, measured δ18O value of quartz; δ18 value of ore-forming fluids in equilibrium with quartz is calculated according to the equation of 1000 reported by Clayton et al. [34]. The temperatures used in calculation are the mean values of the homogenization temperatures from the same quartz samples plus pressure corrected temperatures; that is, (P correction); δ13 values refer to CO2 released from fluid inclusions.
