通过在山西洞沟多金属矿区开展1∶10000土壤地球化学测量工作，首先对测量数据的统计特征进行分析；然后利用Spss软件对其进行相关分析、聚类分析和因子分析，在此基础上确定出工作区内的元素异常组合；最后利用Spss软件作出各元素的盒须图，求出其第1个四分位数和第3个四分位数，从而确定出各元素的异常下限。结果表明：①Au、Ag、Hg、As、Sb、Bi、Ba、Pb、Zn、W等元素含量较高，变异系数较大，具有一定的次生富集倾向；②Ag、Pb、Zn、Mo、Au、Hg、Ba、W等元素代表主要成矿元素的次生富集组合；③通过确定异常下限及圈定各元素异常可知，异常较高的元素均分布在矿区的中部或东部且在构造破碎带内。上述研究结果对于区内进一步开展找矿工作具有一定的指导作用。

Through conducting the soil geochemical survey work in a scale of 1 ∶ 10 000 in Donggou gold-polymetallic deposit area,the statistical characteristics of the survey data is firstly analyzed,and then,the survey data is conducted on corre-lation analysis,cluster analysis and factor analysis based on Spass software so as to obtain the element anomaly combination in the mining area;Finally,the Spass software is adopted to make the box plot of each element so as to determine the anomaly thresholds of each element by obtaining the first quartile and third quartile. The research results show that:①the elements such as Au,Ag,Hg,As,Sb,Bi,Ba,Pb,Zn and W have a certain tendency of secondary enrichment because its contents are higher than other elements relatively,and its coefficients of variation are larger than that of other elements;②the elements such as Ag,Pb,Zn,Mo,Au,Hg,Ba and W elements represent the secondary enrichment combination of the main ore-forming elements;③it is obvious that the high abnormal elements distribute in the central or the eastern part of the mining area and within the tectonic fracture zone by determining the abnormal threshold and selecting the elements′anomalies. The above results can pro-vide some reference for the ore-prospecting work in the mining area.
