摘　　要：采用R型因子分析方法,对大坂山地区水系沉积物地球化学测量所取得的数据进行了统计处理,提取了具有代表性的6种因子组合类型,并利用各因子组合得分值进行了地球化学分区,制作了元素组合分区图,由此将工作区内全部水系沉积物样品所反映的地球化学统计信息以区块的形式反映在一幅图中,通过对该图的判读分析,不仅反映了不同地段中以相应元素组合类型为主的地球化学异常和其地质成因信息,也揭示出相应元素的背景含量特征,为从整体上认识该区地质、地球化学成矿特征提供了简明、清晰的参考资料。Uses the R factor analysis method, obtained the data to the Dabaishan mountain area Geochemical stream sediment survey to carry on statistical processing, withdrew had the representative 6 kind of factors combination type, and scored points the value using various factors combination to carry on the geochemistry district, has manufactured the element combination district chart, from this geochemistry statistics information which the complete river system deposit sample reflected the work area in by sub - area form reflection in a chart, through to this chart analysis, not only had refleeted in the different land sector geochemical anomaly and its geologic origin information by corresponding element combination type primarily, Also promulgates the corresponding element the background value characteristic, for from the whole knew the home court geology, the geochemistry mineralization characteristic has concisely provided concisely, the clear reference.
