| 中文摘要:探测了泥盆系地层覆盖地段Ⅰ号构造带和黑色含矿岩系在深部向西延伸及其倾向埋深展布情况。根据激电测深数据获得“低阻-高极化”特征的断面激电异常曲线图并结合地质资料，解译推测了深部含矿目标层及含矿构造空间赋存状况。经钻探验证，金矿化体位置与激电测深推断的极化率异常中心埋深基本吻合。 |

| Application of IP sounding method to the exploration the Sulinggou gold mining area in South Qinling Mountains |

| Abstract:·The Xiajiadian gold deposit in the South Qinling Mountains contains three mining areas: Xiajiadian, Sulinggou, and Liujiaxia. It is a typical black rock hosted gold deposit with important economic value. In the Sulinggou gold mine area, the IP method was used to detected the distribution of the No.1 structural belt and black ore bearing rock series in the deep westward extension and dip burial depth of the Devonian strata coverage area. Based on the IP sounding data, a cross-sectional IP anomaly curve with "low resistance and high polarization" characteristics was obtained, and combined with geological data, the spatial occurrence status of the deep ore bearing target layer and ore bearing structures was interpreted and inferred. After drilling verification, the location of the gold mineralization body was basically consistent with the burial depth of the polarization anomaly center inferred by the induced polarization sounding. In addition, a database of electrical parameters of rocks (ores) in the mining area has been established. This study has accumulated data for the future exploration of deposits of the same type and characteristics using IP sounding in this mining area and its surrounding areas. |
