| 摘 要： | 对广西金牙金矿床的可溶有机质族组成和气相色谱分析表明，矿体饱和烃的丰度低于围岩，矿体与围岩总抽提物所气相色谱图亦明显不同，尤其是甲醇－丙酮－苯抽提物的区别更明显，矿体与围岩饱和烃丰度的差异为分析有机质在金矿形成过程中的作用提供了线索，对其意义进行了讨论。

| Abstract: | The group composition and the gas chromatographic analyses of the extracts from ore bodies and country rocks in Jinya gold deposit show that the saturated hydrocarbon abundance is higher in ore bodies than in country rocks. The chromatograms of the unfractionated extracts are clearly different, which is especially obvious for the MAB extracts. The difference of saturated hydrocarbon abundance between ore bodies and country rocks provides useful clue for analysing the process of organic matter in the formation of gold deposit. The significance of the difference is discussed in the paper. |
