摘要
用等离子体光度计（ＩＣＰ）测定了广西金牙矿区柱留非烃、非烃、沥青质和干酪根中的金含量，并对矿体和围岩进行了比较。发现在所测组分中，各组分金含量由高到低的顺序为：干酪根、柱留非烃、沥青质、非烃，并且矿体均高于围岩。金在有机质内的分布有两个特点：（１）有机质及其不同组分的金含量与其所在层位的矿化程度呈正相关，如矿体高于围岩；（２）可溶有机质的金含量与其组分的极性呈正相关，如抽提物中柱留非烃的极性最大，其金含量最高。
The Au content of column held nonhydrocarbon,nonhydrocarbon,asphaltene and kerogen in Jinya Gold Deposits in Guangxi province was measured by the Plasma actinometer (ICP)in the paper.The comparison of measured information between ore bodies and country rocks shows that the components which have the Au content order from high to low are kerogen、column held nonhydrocarbon、asphaltene and nonhydrocarbon,and that the Au content is higher in ore bodies than in country rocks.Gold distribution in the organic matter shows two characteristics:1.the Au content in organic matter and in different components has a positive correlation with the mineralization degree of their host horizon,such as higher Au content in ore bodies than in country rocks.2.the Au content in the extracts has a positive correlation with the polaritry of their host components,such as the highest Au content cohumn held nonhydrocarbon which has the biggist polarity in the extracts.
