摘　　要：七里山金矿区位于胶西北灵北断裂带南西段,其探矿深度已超过地表下500 m。本次研究制定了针对深部隐伏矿体定位预测的地、物、化多元异常信息找矿方案。物探选择了大地电磁测深法,共测量了4条剖面;化探采用的是构造地球化学法。依据Au、As、Sb等元素的构造地球化学异常及大地电磁测深法所获得的电阻率异常信息,结合地质分析圈定出深部找矿靶区3处。Qilishan Gold District is located in the southwest of Lingbei fault zone,and its prospecting depth reaches over 500 m below the surface. The ore exploration scheme,which includes geology,geophysical prospecting and geochemical prospecting,was established for deep concealed ore bodies positioning based on multiple anomaly information. Audio magnetotelluric（ AMT） was chosen as the geophysical prospecting method and measured 4 sections. The tectonic geochemistry method was chosen as the geochemical prospecting method. 3 deep prospecting targets were delineated according to the structure of the geochemical anomalies of Au,As,Sb,etc. and the low resistivity anomaly from magnetotelluric sounding method in combination with geological analysis.
