摘要: 槐树坪金矿是赋存于熊耳群缓倾斜层间挤压破碎带内的石英脉+蚀变岩型金矿床。热液成矿过程可划分为3个阶段：Ⅰ.乳白色石英脉-团块状黄铁矿阶段；Ⅱ.烟灰色石英脉-多金属硫化物阶段；Ⅲ.石英-碳酸盐脉阶段。对流体包裹体进行显微测温和拉曼光谱分析，研究表明，Ⅰ、Ⅱ成矿阶段石英中流体包裹体主要发育CO2-H2O型、纯CO2型和NaCl-H2O溶液型包裹体，Ⅲ成矿阶段石英中主要发育NaCl-H2O溶液型包裹体，成矿Ⅰ阶段到Ⅲ阶段包裹体均一温度变化为189~439℃→145~351℃→145~267℃，盐度变化为6.98%~10.29%→2.03%~11.71%→2.89%~15.04%，成矿早阶段流体由中温、中低盐度H2O-NaCl-CO2体系向晚阶段低温、低盐度NaCl-H2O体系演化。判定成矿流体来源于岩浆热液，具有深源特征。成矿流体中金主要以Au（HS）形式迁移，其次为Au2（HS）2S2-。Abstract: The Huaishuping gold deposit is a quartz vein gold deposit, which was occurred in slowly inclined interlayer extrusion zone of Xiong'er Group. Hydrothermal ore-forming process of this deposit can be divided into three stages:stage Ⅰ-milky quartz vein-phase crumb pyrite quartz vein, stage Ⅱ-smoke gray-polymetallic sulfide phase, and stage Ⅲ-quartz-carbonate phase. Through the studies of fluid inclusion microscopic temperature measurement and Laser-Raman spectra analysis, the results show that:three types of fluid inclusions in stage Ⅰ and Ⅱ are identified as CO2-H2O type, pure CO2 and NaCl-H2O solution type,while stage Ⅲ quartz inclusions main contain the NaCl-H2O solution type. From the metallogenic stage Ⅰ to stage Ⅲ, the homogenization temperatures of fluid inclusions are 189~439℃→145~351℃→145~267℃, while their salinities are 6.98%~10.29%→2.03%~11.71%→2.89%~15.04%. The ore-forming fluid was evolved from H2O-NaCl-CO2 system,which is characterized by changing from medium temperature and medium-low salinity to low temperature and salinity NaCl-H2O system. It's determined that the ore-forming fluid was derived from magmatic hydrothermal, which has the characteristics of deep source. And then, it's suggested that the ore-forming fluid was mainly migrated in the form of Au (HS), secondly by Au2(HS)2S2-.
