| 摘 要： | 从矿石和围岩可溶有机质的生物标志化合物，非烃的红外光谱学特征，以及有机包裹体的光学和谱学特征等方面论述了金牙金矿的有机地球化学特征及其有机流体的成矿作用，查明了参与成矿的有机质主要来源于菌藻类等低等生物，本有机质的成分、结构、成熟度和胡成矿作用的进行而不断演化。在有机碳、金含量及藻类成矿作用模拟实验的分析基础上，认为流体有机质参与成矿的方式主要是活化萃取、还原沉淀，而干酪根则对金起集作用。

| Abstract: | In order to guide the mineral exploration based on the relationship between the organic matter and the mineralization, this paper deals with the properties of organic matter occurring at Jinya gold deposit Guangxi through biomarkers, organic inclusion, the spectrum of the non hydrocarbons and the simulation experiment. The preliminary study shows that bacteria and algae play an important role in mineralization. The component and structure of organic matter trapped in the fluid inclusions varied with its maturity. Based on the contents of organic carbon and gold and the simulation experiment, the authors deem that the organic matter was involved in mineralization process through extraction, reduction precipitation and accumulation. |
