水系沉积物测量是勘查地球化学一种重要方法。随着勘查地球化学的深入发展，有关地球化学异常圈定的方法已成为人们关注的焦点。采用R型因子分析方法，对哈拉奇地区水系沉积物测量所取得的数据进行统计处理，提取了具有代表性的5种因子组合类型，同时以因子得分为综合指标，绘制了因子得分等值线图并制作了元素组合分区图。通过综合分析，地球化学分区图反映了不同地段中以相应的元素组合类型为主的地球化学异常及地质成因信息，同时与主要控矿因素的空间分布比较一致，为研究区地质找矿提供新方向。

Stream sediment survey is an important method of exploration geochemistry. With the deep develop-ment of exploration geochemistry, the geochemical anomaly delineation and evaluation have become the focus of the attention. Used the R factor analysis method, obtained the data from Halaqi region Geochemical stream sedi-ment survey to carry on statistical processing, get the representative 5 kind of factors combination type, and by us-ing factor score for the composite indicator, protracted contour maps of the factor score and the geochemical sub-divisions map. The maps reflected the different land sector geochemical anomaly and its geologic origin by corre-sponding element combination type primarily, and the same with space distribution of the main metallotect. The research provided new information for geological prospecting in the study area.
