摘　　要：简述激发极化法的基本原理。马鞍桥金矿床为浸染型金矿床,根据矿化岩石与围岩间存在明显的电性差异特征,选用激发极化法进行测量,并结合地质、化探等方法,结果表明,激发极化法不仅可以直接发现金矿化带、矿(化)体,而且还能反映隐伏的金矿(化)体地质特征,其地质找矿效果明显。In this paper,the foundational principle of induced polarization method is simply summarized.Maanqiao gold mine is a disseminated gold deposit.Based on the obvious difference of electrical property between the mineralized rock and the wall rock,by using the central gradient of induced polarization method,combined with geological and geochemical exploration method,it shows that by the induced polarization method,not only gold deposit belt would be found directly,but also the geological characteristics of the concealed gold ore body would be reflected.Thus the method is available for the geological prospecting.
