摘　　要：有机质对金属元素的迁移、沉积、富集成矿有重要的作用 ,有机烃是有机质最终的裂解产物 ,具有很强的挥发性和穿透性。研究发现八卦庙金矿床有机烃与金矿体品位呈正相关关系 ,矿床的矿化富集中心也是有机烃的浓集中心 。Organic matter plays an important role in the transport, deposition and enrichment of metal elements. Organic hydrocarbon is the final pyrolysis product. It is found that organic hydrocarbon has a positive correlation with gold content of orebody in the Baguamiao gold deposit. The mineralizing and enrichment center of the gold deposit is also the concentration center of organic hydrocarbon. The characteristics of organic hydrocarbon can be used to search for concealed gold deposits.
