Abstract: 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 undulation 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.

Key words: structure geochemistry, element association, qualitative variable, factor analysis, cluster analysis, synthesized information
