陕西石泉北部将军河地区石英脉发育，具有多期特征。目前，发现了大石板沟、叶家坡、青泥涧等多处金矿化点，金矿化与石英脉关系较密切。划分石英脉的形成期次，对比研究各期石英脉包裹体地球化学特征，对工作区找金矿具有重要指导意义。研究显示将军河地区第一期石英脉(顺S1面理产出)包裹体为中低温(170~220℃)和较高盐度；第二期石英脉(顺 S2面理产出)包裹体为中高温(270~370℃)和较高盐度；第三期石英脉(顺 S3面理产出)包裹体为中低温(170~220℃)和较低盐度；区域上金矿分布主要与第二期石英脉展布方向一致，长沟、羊坪湾金矿床中含金石英脉包裹体为中低温和较低盐度。通过采样分析，发现将军河地区第二期石英脉形成温度和盐度较高，金矿化较贫，今后找金矿应该重视中低温和较低盐度的石英脉包裹体地段。%Dashibangou,Yejiapo and Qingnijian gold mineralization points were discovered in Jiangjunhe area of Shiquan County in Shaanxi Province.Multi-stage quartz veins may relate to the gold mineralization.To discriminate the periods of quartz veins and geochemical characteris-tics of their inclusions has important significance for future prospecting in the study area.The re-search results show that the first-period quartz veins (occurrence parallel to S1 foliation)host fluid inclusions characterized by mesothermal-low temperature (170 to 220℃)and fairly high sa-linity;the second period quartz veins (occurrence parallel to S2 foliation)host fluid inclusions characterized by mesothermal-high temperature (270 to 370℃)and higher salinity;the third peri-od quartz veins (occurrence parallel to S3 foliation)host fluid inclusions characterized by meso-thermal-low temperature (170 to 220℃)and lower salinity.The regional gold deposits mainlydistribute along the second period quartz veins,and the quartz veins of Changgou and Yangping-wan gold deposits have mesothermal-low temperature and lower salinity fluid inclusions.Howev-er,the second period quartz veins in Jiangjunhe district are characterized by mesothermal-high temperature and higher salinity and poor gold grade.So,more attention should be paid to the ar-ea with mesothermal-low temperature and lower salinity quartz veins in future prospecting.
