摘　　要：通过对内蒙古扎赉特旗哈拉街吐铜多金属矿区进行1/2.5万土壤地球化学扫面工作,对Mo、Cu、Pb、Zn、Ag、Cr、Ni、Sn、Sb、As等元素数据进行元素的含量特征参数、概率分布特征、蚀变与矿化叠加系数、元素间相关关系和聚类群组等特征统计并绘制异常图,研究了矿区的土壤地球化学特征及异常特征。根据地球化学异常分类的一般准则,综合考虑地球化学异常的规模、形态、异常的强度、分带性、异常元素的组合及异常所处的成矿地质和地球化学条件,圈出乙级异常3个(I号、III号、V号异常区),丙级异常区2个(II号、IV号异常区)。By soil geochemistry reconnaissance of 1/25 000 in Halajietu copper polymetallic mining area in Jalaid county,Inner Mongolia.Statistical characteristics were observed according to the characteristic parameters of elements,probability distribution,alteration and mineralization superposition coefficient,correlations between elements,clustering group of Mo,Cu,Pb,Zn,Ag,Cr,Ni,Sn,Sb as elements data was done and the anomaly map was drawn.The soil geochemical characteristics and abnormal characteristic of this area were mainly found out according to the general rule of classification of geochemical anomalies.Considering the scale of geochemical anomalies,morphology,abnormal strength,zoning,abnormal element combination,the ore-forming geological anomalies and geochemical conditions,we can find out three B abnormal areas（I,III and V）and two C abnormal areas（II,IV）,providing geochemical basis for the next step of mineral exploration work.
