摘　　要：矿床石英脉中发育3种类型的流体包裹体:C型、PC型及W型包裹体。测温结果显示:早阶段C型包裹体均一温度为340℃~480℃,盐度为6.1%~9.1%NaCl_(eqv);中阶段3种类型的包裹体均发育,均一温度为220℃~460℃,盐度5%~15.2%NaCl_(eqv);晚阶段只发育“W”型包裹体,均一温度为140℃~300℃,盐度为1.1%~8.1%NaCl_(eqv)。萨热阔布金矿床受阿巴宫断裂构造控制,整体呈脉状产于韧性剪切带内,流体以中-低温、低盐度、富CO_(2)为特征,与造山型矿床的流体特征十分相似,因此认为萨热阔布金矿为造山型金矿床。Three types of fluid inclusions are developed in the quartz veins of the deposit:C-type,PC-type and W-type inclusions.The temperature measurement results show that the homogenization temperature of C-type inclusions in the early stage is 340℃~480℃,and the salinity is 6.1%~9.1%NaCl_(eqv);the three types of inclusions in the middle stage are all developed,and the homogenization temperature is 220℃~460℃,and the salinity is 5~15.2 NaCl_(eqv);only W-shaped inclusions developed in the late stage,the homogenization temperature is 140℃~300℃,the salinity is 1.1~8.1NaCl_(eqv),the Sarekuobu gold deposit is controlled by the Abagong fault structure,and the whole vein is produced in ductile shear.In the cut zone,the fluid is characterized by medium-low temperature,low salinity,and rich CO_(2),which is very similar to the fluid characteristics of orogenic deposits.Therefore,the Sarekuobu gold deposit is an orogenic gold deposit.
