摘　　要：根据岩矿石物性特征,测区投入高精度磁测和大功率激电两种方法寻找主矿体。根据负、低磁异常追踪磁性不强的含金矿带、追索控矿破碎带反应的低磁带,圈定具弱磁性的金矿体,根据低电阻率和高极化率圈定原生金矿中伴生的黄铁矿化多金属硫化物等,从而达到寻找主矿体的目的。Based on the rock physical property feature,high-precision magnetic measurement and high-power IP can be used in the survey area to prospect the main ore body.To delimit the gold ore body with low magnetism,we can trace the low magnetic gold ore and locate the low magnetic region in the fractured area of the controlled ore by detecting abnormally negative or low magnetism.Furthermore,using low resistivity and high polarizability to locate the associated pyritization polymetallic sulfide in the primary gold ore,the goal of finding the main ore body will be achieved.
