摘　　要：阳沟金矿床地处辽东古元古代裂谷北部与太子河-浑江拗陷带接壤部,该区老地层发育且存在铜、铅、锌等综合化探异常,受地表植被影响找矿工作进展缓慢。区内岩矿石极化率和电阻率差异明显,具备利用电性特征进行大功率激电测量的地球物理勘探条件。通过于区内开展大功率激电测量工作,圈定低阻高极化异常区3个、高阻高极化异常区1个。A异常区内探槽和钻探验证工程均显示出良好的矿化信息,圈定出矿石品位较高、长度超过100 m、宽0.3~0.91 m的矿体1条。大功率激电测量在辽宁阳沟金矿床勘查圈定有利成矿地段、寻找隐伏矿体工作中可发挥重要的作用。The Yanggou gold deposit was located in the northern part of the Paleoproterozoic rift valley bordering the Taizihe-Hunjiang depression belt in eastern Liaoning Province.The old strata in this area were developed and there existed comprehensive geochemical anomalies such as copper,lead and zinc.The prospecting work progresses slowly due to the influence of surface vegetation.There existed obvious differences in the polarizability and resistivity of rock and ore in the area,and it was feasible to use electrical characteristics to measure high power IP.By carrying out high-power IP measurement work in the region,three lowresistance and high-polarization abnormal regions and one high-resistance and high-polarization abnormal region were delineated.The exploration trough and drilling verification engineering in abnormal area A showed good mineralization information,and one ore body with high ore grade,over 100 m in length and 0.3~0.91 m in width was delineated.High power IP survey could play an important role in delineating favorable ore-forming areas and searching for concealed orebodies in the exploration of Yanggou gold deposit in Liaoning province.
