【摘要】 老柞山金矿是黑龙江重要的黄金产地之一。本文对该金矿床的成矿地质背景和硫同位素、铅同位素、碳和氧同位素的组成特征进行了分析研究。结果显示成矿流体类型为来源于壳幔同熔的混合含矿岩浆热液,成矿物质主要来自幔源或少量地壳物质。矿石和岩浆岩具有非常相似的铅同位素组成,暗示了二者的亲缘关系。在综合已有地质资料的基础上,对矿床的成因模式进行了总结,强调该矿床的形成是多次构造岩浆逐步富集而成。更多还原

【Abstract】 This paper deals with the Laozuoshan gold deposit,one of the important gold mines in Heilongjiang province,its geological background and isotopic elements such as sulphur,lead,carbon,and oxygen.The studies indicate that the ore-bearing fluid is magma with minor crust and major mantle substances.The ore and the magma share similar lead isotopic features which suggests a close relations between them.The authors consider that the Laozuoshan gold deposit is resulting from multiple tectono-magmtic activities.更多还原
