 The Luoli gold deposit in Liping County of southeastern Guizhou Province is a low-sulfide gold-bearing quartz deposit. The characteristics of geology, quartz fluid inclusions homogenization temperature, salinity, and Raman spectrum suggest that the deposit formation process can be divided into 4 stages: vein formation stage, mineral formation stage, carbonate stage and supergene stage. The fluid inclusion composition is dominated by H₂O, CO₂, CH₄, and N₂. When the mineralization fluid of Au rose to the shallow subsurface along fissures, it caused metasomatic alteration with surrounding rocks, separating the fluids rich in H₂O and CO₂. In a certain sense, the content of CO₂ can be used as an indicator for the exploration of gold deposits of quartz-vein type.
