| 摘 要： | 在栾川铅锌矿的物探工作中，采用了电阻率层析成像和激电测深两种方法，电阻率层析成像法采用温纳装置或偶极装置，电极数量和极距视情况而定，主要调查工作区内隐伏构造情况，激电测深采用对称四极测深法，最小AB／2距为3M，最大AB／2距为500M，主要研究激电测深参数的变化规律，对于含矿构造而言，激电参数呈异常高值反映，视极化率在15－40％，两种方法的联合应用，具有快速而准确的特点，在探矿工作中取得了良好的效果。

| Abstract: | In exploration of Lead-zinc deposit in Luanchuan region, both the resistivity tomography and the electrical sounding of induced polarization methods are used. The hidden structures in the studied region are mainly prospected by the resistivity tomography method that uses dipole-dipole of the high density resistivity survey system, in which number of electrodes and pole spacing are decided according to actual conditions. Variation regularity of induced polarization parameters is mainly studied by using symmetry 4-pole electrical sounding method, in which the minimum distance of the AB/2 is 3 m, and the maximum distance of the AB/2 is 500 m. For ore bearing structures, the induced polarization parameters show high anomaly, and the apparent polarizabilities are between 15% and 40%, combining these two methods, we could obtain quickly and exactly the satisfactory results of prospecting for the mine in the studied region. |
