| 摘 要： | 根据内蒙古四五牧场金矿床的S、Pb、O、C同位素组成特征，对金矿床成矿物质来源进行了分析.认为金属硫化物中的硫来源于火山岩盆地基底古生代海相地层；铅主要由赋矿地层及火山岩盆地基底岩石所提供；成矿流体在成矿期主要来源于岩浆，成矿期后热液中有大气水混入.四五牧场金矿成矿期为晚侏罗-早白垩世.

| Abstract: | Based on the characteristics of S, Pb, O and C isotope in the Siwumuchang gold deposit in Inner Mongolia, the ore-forming material resource is analyzed. It is concluded that the S in metallic sulfides comes from the volcanic rock basin of Paleozoic marine bed. The Pb is provided by host strata and volcanic rock basin. In mineralization period, the ore-forming fluid is mainly derived from magma, with meteoric water mixed after the mineralization. The mineralization period of the Siwumuchang gold deposit ranges from Late Jurassic to Early Cretaceous. |
