摘　　要：一些文献列举了新疆阿希和石英滩金矿床群体包裹体成分分析结果 ,其阳离子中Na+ /K+ 比值 (原子比 ) <1,并存在大量过剩阳离子等与矿床地质特征相悖的特点。文章利用群体包裹体分析方法 ,对阿希金矿含金石英脉进行了专门的实验 ,结果证实上述分析结果与分析样品不纯和非包裹体来源的污染有关。文中还讨论了有关包裹体成分分析和结果应用中值得注意的一些问题。The compositions of fluid inclusions in the Axi and the Shiyingtan epithermal gold deposits, Xinjiang, are reported in literature. These inclusions are characterized by the inequality K +/Na +>1 and the apparent imbalance between cations and anions. These features are not consistent either with the geological characteristics of the deposits or with the compositions of fluid inclusions in other epithermal gold deposits of the world. Based on experiments, it is held that the inequality K +/Na +>1 and the charge imbalance are attributed to impurity of samples and contamination. Some problems which deserve further attention in determining the composition of fluid inclusions and the application of the result are also discussed in this paper.
