| 摘 要： | 内蒙古赛乌素金矿是产于中-新元古代白云鄂博群变质碎屑岩中的石英脉型金矿,矿床稳定同位素地球化学特征表明,成矿热液来源复杂,可能有岩浆水和大气降水的混合作用;成矿早期的硫来自花岗岩浆,成矿晚期的硫有一部分可能来自地层,铅同位素特征表明铅来自地幔,因此推断成矿物质主要来自于岩浆活动.

| Abstract: | Saiwusu gold deposit,located in central Inner Mongolia,is a medium-size quartz vein type gold deposit associated with metamorphic clastic rock in the Middle-Upper Proterozoic Bayun Obo Group.H,O,S,Pb isotopes were analyzed and discussed.The results show that: ore-forming fluid maybe originated from magmatic water and meteoric water;sulfur from granite in the early stage and from sedimentary sequence in the late stage;lead from mantle.Thus,the author considers that ore-forming materials are from magmatic activity. |

| Keywords: | stable isotopes origin of ore-forming materials Saiwusu gold deposit Inner Mongolia |
