摘　　要：近几年,在内蒙正镶白旗发现了多处银铅锌矿床,为进一步了解该地区银铅锌矿床地质构造、地球物理及地球化学特征,以1∶5万区域地质调查中圈定的化探异常为基础,对研究区开展了土壤测量、高精度磁测、激电中梯测量等工作,获得实测数据。通过对磁测数据进行化极、延拓、求导等处理,圈定磁异常形态,对盖层下地层界限及构造特征进行分析研究;Ⅰ号银铅锌矿化体激电测深反演结果与矿化体赋存特征相吻合。通过钻探验证,综合物化探方法取得了较好的找矿效果,指明了找矿方向,为该地区下一步寻找铅锌银矿床起到一定的指导作用。In recent years,many silver-lead-zinc deposits have been discovered in Zhengxiangbai Banner,Inner Mongolia.In order to make further understanding of the geological structure,geophysical and geochemical characteristics of the silver-lead-zinc deposits in this area,we carried out the soil survey,high-precision magnetic survey,and IP mid-ladder survey are carried out to obtain actual measured data on the basis of the geochemical anomalies delineated in the 1:50000 regional geological survey.By polarization,continuation,and derivative processing treatment of magnetic survey data,the magnetic anomalies are delineated,the boundary and structural characteristics of the overlying strata is analyzed and studied.The inversion result of the induced polarization sounding of the No.1 silver lead zinc mineralization body is consistent with the occurrence characteristics of the mineralization body.Through drilling verification,the comprehensive geophysical and geochemical exploration method has achieved a good prospecting result.The prospecting direction is pointed out.It provides a reference for the next step of lead-zinc silver deposit exploration in the area.
