青海省鸭子沟铜多金属矿区花岗闪长岩及其滩间山群碳酸盐岩发育，是形成矽卡岩型铜多金属矿（化）体的主要控矿因素。结合区域地质、地球物理及地球化学特征，在其所判定的成矿远景区，开展了以激电中梯和地面高精度磁测为组合方式的综合物探找矿实践。利用激电中梯扫面方式圈定出激电异常体，利用地面高精度磁测来了解区内主要地质体的磁性特征，在主要剖面上部署激电测深剖面，指导钻探工作进行。勘探结果表明找矿方式效果显著、经济高效，对同类地质成矿地区的隐伏多金属矿勘探工作具有一定的参考价值。

The Yazigou copper?polymetallic deposit is located in Yaziggou area, Mangya Town, Qinghai Province. The development of granodiorite and Tanjianshan Group carbonatite in the area constitutes the main ore?controlling factors to form skarn type copper?poly?metallic orebodies. Based on regional geologucal, geophysical and geochemical features, the authors employed the IP intermediate gra?dient method and the ground high?precision magnetic comprehensive geophysical prospecting method in search for ore deposits in the predicted metallogenic prospect areas. IP intermediate gradient method was used to delineate IP body anomaly, and ground high?preci?sion magnetic measurement was adopted to detect the magnetic features of main geological bodies in the area. Along the important geo?logical sections, IP sounding was used to guide drilling work. Practice indicates that this method is very effective and efficient, and has the reference value for exploration of concealed polymetallic deposits in similar metallogenic regions.
