摘　　要：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。The evolutional characteristics of geochemical elements during the metallogenic process can be guessed through the statistical analysis of geochemical elements'data suppling useful concealing messages. The researches of cluster analysis and factor analysis in this paper reveal that there aren't correlativity among Au and other elements except Bi, the mineralization of gold had undergone long period and many times geological evolution process. It is considered that Bi is proximal indicator element and As is distal indicator element for exploring gold in the mine according to the association and correlative character of elements.
