Fluid inclusion observations were made using a conventional optical petrographic microscope to document its paragenetic relationship to ore minerals and morphology. The microthermometric measurement of fluid inclusions trapped in quartz was made using a Linkam THMSG 600 stage at IGCAS, calibrated at −56.6 °C, 0 °C, and …

The ore-forming fluids belonged to the H 2 O-NaCl ± CO 2 system. (3) The δ 18 O H2O and δD H2O values of stage II-IV range from −9.9 to −5.2‰ and −121.9 to −119.8‰, respectively, indicating that the ore-forming fluids were driven by intermediate-felsic magmatic water and mixed with meteoric water during mineralization.

The ore-forming process includes three stages: albite–quartz–pyrite stage, quartz–polymetallic sulfide stage and barren quartz–carbonate stage. The fluid inclusions in the early- and middle-stage quartz are mainly aqueous inclusions and CO 2 –H 2 O inclusions, while only aqueous inclusions are developed in the late-stage quartz.

With the adjusted LCI and the inclusion of copper sulfate, the GWP for the Reference process was 15.1 t CO 2-eq/kg Au, whereas the originally calculated value was 12.6 t CO 2-eq/kg Au (Elomaa et al. Citation 2020a). The difference is explained principally by the addition of copper to the LCI data.
