【摘要】 通过对野外地质特征及流体包裹体研究,将本区成矿过程分为3个成矿阶段:石英-黄铁矿阶段、石英-多金属硫化物阶段及石英-碳酸盐阶段。包裹体类型主要为富液相包裹体(LV型)。石英-黄铁矿阶段均一温度主要集中于290℃~330℃,盐度变化范围为0.35%~11.23%,平均值为5.37%;石英-多金属硫化物阶段的均一温度主要集中于290℃~330℃,盐度变化范围为0.35%~11.23%,平均值为5.37%;石英-碳酸盐阶段温度均一温度主要集中于133℃~201℃,盐度变化范围为2.23%~12.07%,平均值为4.96%。成矿流体在初始阶段为较高盐度的岩浆流体,属于中-低温、低盐度的H2O-NaCl体系,随着成矿作用的进一步演化,晚期有大气降水的参与。更多还原

【Abstract】 Based on the study of geological characteristics and fluid inclusions,the ore-forming process can be divided into 3metallogenic stages,quartz pyrite stage,quartz polymetallic sulfide stage and quartz carbonate stage.The main type of fluid inclusions is rich liquid inclusions(LV type).Quartz pyrite stage homogenization temperature is mainly concentrated in 290℃-330℃,the salinity range changes from 0.35%to 11.23%,the average value is 5.37%.The homogenization temperature of quartz polymetallic sulfide stage is mainly concentrated in 290℃-330℃,the salinity range changes from 0.35% to 11.23%,the average value is 5.37%.The quartz-carbonate stage homogenization temperature is mainly concentrated in 133℃-201℃,the salinity range changes from 2.23% to 12.07%,the average value is 4.96%.The ore-forming fluid in the initial stage is magmatic fluids of high salinity,which is belonged to H2O-NaCl system of low-middle temperature and low salinity.With the further evolution of mineralization,atmospheric precipitation is involved in the late stage.更多还原
