In recent decades, gold resources near surface has been almost completely exploited. The induced polarization method can more accurately predict the deep ore body. Especially gold most together with metal sulfides. Sulfide use to be pyrite and it could be pyrrhotite occasionally. By using induced polarization it can work out the physical field of the associated ore. United the physical field with geology theory, we can back stair working out whether there could be a Gold mine and the details of the Gold mine.%近几十年来，近地表金矿资源近乎被开发殆尽，寻找深部隐伏金矿已经成为近年来金矿勘探中的重点方向。利用激发极化法能够较准确的预测深部隐伏矿体的存在。特别是金矿大多数与金属硫化物伴生，硫化物通常是黄铁矿或毒砂，偶尔也有磁黄铁矿，使用激发极化法测量这些伴生矿的物理场特征，结合地学理论就可以间接找出金矿。
