摘　　要：为研究胶东地区山城金矿的控制因素和预测隐伏矿体,利用R型因子分析和聚类分析揭示了各种地质和地球化学变量的关系。同时,针对聚类分析中难以有效显示变量间负相关问题提出了反序变换的方法。结果表明,该矿的黄铜矿化、脉状黄铁矿化、Au-Ag-Cu组合与As-Sb-Hg组合相关,并受主构造面走向波动控制;而较厚石英脉、菱铁矿化、星散状黄铁矿化、Pb-Ba组合与Co-Ni组合相关,并受主构造面倾向波动控制。这些结果与地质结论一致,但研究方法更简便快捷。In order to study the ore-controlling factors and to prospect the hidden ore bodies at Shancheng gold deposit in Jiaodong Area, the relationships between geological and geochemical variables are revealed by using R-mode factor and cluster analyses. Meanwhile, a method called order-reverse transform is developed to solve the problem that the negative correlation between variables can not be shown in cluster analysis. The results show that the mineralization of chalcopyrite and nervate pyrite, associations of Au, Ag, Cu and As, Sb, Hg are related, and are controlled by the lengthways undula- tion of the main structure surface in this deposit; and that the thick quartz vein, the mineralization of siderite and granule pyrite, associations of Pb, Ba and Co, Ni are related, and are controlled by the dip undulation of the main structure surface. These results are consistent with geological conclusions, but its studying processes are more convenient and rapid.
