摘　　要：内蒙古四子王旗哈布其亥地区位于半干旱草原区,地表出露较差,地质找矿标志不明显,在找矿过程中综合物化探方法对发现矿体起到了重要作用。化探测量发现研究区主要成矿元素Cu、Pb、Zn,伴生元素As、Sb、Sn、Bi异常分布面积大,综合异常复杂,浓度分带明显。通过激电中梯测量确定矿体赋存在断裂构造中;通过综合剖面异常查证,主要成矿元素异常重现性较好;通过钻探工程对物化探异常进行验证,在深部发现了锌铜多金属矿体;因此物化探异常成为研究区的重要找矿标志。总结该矿床的地质、物化探特征,提出对半干旱草原区的找矿方法,为本地区的进一步找矿工作提供借鉴。The study area is located in the semi-arid prairie region of Inner Mongolia.The rock outcrop is poor,geological prospecting sign is not obvious.In the process of ore-prospecting,the integrated geophysical and geochemical methods plays an important role in the delineation of orebodies.Geochemical survey shows that the major oreforming elements are Cu,Pb,Zn and Bi,associated elements are As and Sb.Anomaly area is large,the comprehensive anomaly are complex,and the concentration zoning of the anomalies is obvious.The induced polarization intermediate gradien survey shows the ore bodies occur in the fault structures.Through the verification to the comprehensive profile anomalies,the repeatability of anomalies of main metallogenic elements is better.Through the drilling engineering to verify the geophysical and geochemical anomaly,the zinc and copper polymetallic ore bodies are found in the deep part.The geophysical and geochemical anomalies are the important indicators for ore-prospecting.This paper summarizes the geological,geophysical and geochemical characteristics of the deposit,and puts forward the prospecting method in the semi-arid prairie region of Inner Mongolia,and provides reference for further prospecting in this region.
