通过对地化元素量值的统计分析可以推测地化元素在成矿过程中的演化特征，进而为预测找矿提供有用的深层次信息。本文通过有关元素的聚类分析、因子分析研究揭示界河矿区内Ａｕ与Ｂｉ以外的其他元素基本不具相关性、Ａｕ的成矿经历了长期、多次的地质演化过程，揭示了矿区内仅Ａｕ独立成矿的内在原因。文中据元素的共生组合及相关性特征认为矿区内Ｂｉ可作为找金的近程指示元素，Ａｓ可作为找金的远程指示元素。 Through the statistical analysis of the values ​​of the geochemical elements, we can speculate the evolution characteristics of the geochemical elements in the metallogenic process and provide useful and deep information for the prospecting prospecting. In this paper, through cluster analysis of relevant elements, factor analysis revealed that there is almost no correlation between Au and other elements in Bihe mining area. Au mineralization underwent long-term and repeated geological evolution, revealing that only Au The inner cause of mineralization. According to the symbiotic assemblages and correlation features of the elements, Bi can be used as a short-range indication element for finding gold in the mining area, and As can be used as a remote indication element for finding gold.
