摘　　要：长春市兰家金矿床是已开采多年小型金矿床,为了增加储量在其外围利用物探方法进行勘查,发现了极化率4%～6%,电阻率<1 000Ω的高极化率低阻异常区。经钻探工程和地表工程验证发现金矿(化)体与异常解译基本吻合。说明利用物探激电方法可以快速直接指导找矿,达到一定成果。Lanjia gold deposit of Changchun City is a small gold deposit has been mined for many years,in order to pursue a higher reserves on its peripheral utilization of geophysical and geochemical method for scanning,found the polarization rate of 4%～6%,resistivity 1000 Ω high polarization rate low resistance anomaly.Drilling engineering and surface engineering verification found that gold is coincide with abnormal interpretation.iIt shows that the use of geophysical IP sweep surface can be quickly and directly guide the ore prospecting,and can reaches a certain achievement.
