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矿体金品位呈正相关关系，矿体的矿化富集中心也是有机烃的浓集中心．利用有机烃的这一特点可以进行隐伏金矿床的预测研究。Organic material plays an important role in the migration, precipitation, enrichment and mineralization process of metallic elements. Orgnic hydrocarbon, with strong volatility and penetrability, is the final product of organic material splitting. The study for Baguamiao gold deposit reveals that the organic hydrocarbon is positively correlated to the gold grade of ore. The mineralizing center of the deposit coincides with the concentrating center of organic hydrocarbon. This character of organic hydrocarbon may be applied to prognosis for hidden gold deposits.
