摘　　要：构造地球化学特征研究是指导矿山深部找矿的有效手段。在深入研究矿区地质的基础上,对矿段内地表断裂构造原生晕数据进行了R型聚类分析和R型因子分析,根据R型因子分析的结果——因子得分值,圈定了四组因子得分的综合异常图。其结果表明,元素组合异常明显,呈NE向带状展布;主要成矿元素及相关指示元素组合出现多个异常浓集中心,并与已知深部矿体产出空间能较好地对应。这些特征的分析对指导矿山生产和找矿具有现实意义。The research on structure geochemical characteristics is effective for guiding ore finding in deep part of mines. Based on the thorough mining geology research, R cluster analysis and R factor analysis are used to process surface tectonic primary halo data, and made comprehensive anomaly maps of four factor group score according to the result of R pattern factor analysis----factor sore values. The result shows that the element combination anomalies are distinct, and extend to be zoned in northeast direction. There are several accumulation centers of the major ore elements and the relevant indicator element combinaitons, which are homologous with many known deep-ores. It is of realistic significance for the study of these characteristics to guide mine production and further prospecting.
