%X There are abundant CO 2 H 2O fluid inclusions in Yanshanian Wenyu granite which is known to be related with gold mineralization, showing that fluids are enriched in CO 2 with lower density (<10wt%NaCl) and similar to fluid inclusion types and fluid nature in gold bearing quartz veins. Fluid inclusions in Huashan granite, which is not related with gold mineralization, are aqueous type with poor CO 2 and low salinity. Less CO 2 H 2O inclusions are developed in Liangliangshan granite, which has relations with gold mineralization but poor gold veins occurring in nearby metamorphic rocks. CO 2 H 2O inclusions can be used as symbol to identify relationship degree between granite and gold mineralization, and CO 2 H 2O inclusion abundance can be practiced to evaluate gold grade, mineralizing scale and exploration potentials.
