| 摘 要： | 在前人研究的基础上,对扬子西缘卡林型金矿采用稳定同位素和生物化学试验方法,分析赋金地层中有机质的种类、性质和有机质与金矿的关系,讨论有机质在金元素富集、迁移、成矿过程中的作用.认为赋金地层与后期岩浆热液发生广泛的交换作用,萃取出成矿物质形成成矿流体,这种富含成矿物质的热液流体在一定的条件下富集成矿.

| Abstract: | Since 1970s,Carlin-type gold deposits have been discovered in the southwestern Yangtze Craton in China.Many predecessors made researches on the ore-forming materials and metallogeny.On basis of the researches this paper applies stable isotope and biochemistry and combines the analysis of the types and nature of organic matter in the ore-bearing strata and studies on the relation between organic matter and gold deposits to discuss the role of organic matter in accumulation and transportation for the gold.A wide-ranging exchange occurred between the ore-bearing strata and the late magmatic hydrothermal fluid with gold-minerals extracted to form Carlin-type gold deposits under certain conditions. |
