激电中梯测量在新疆穆呼锰矿区找矿应用分析

Analysis of prospecting application of IPR ladder in Xinjiang Muhu manganese mining area

为了研究锰矿体及目标矿带的延伸情况,在工作区先后开展了1:2000激电中梯剖面测量、1:1万激电中梯剖面测量工作。研究总结了“高幅频率(大于3%)、中低电阻率(250Ω.m左右)、弱磁负异常(-100nT至100nT之间)”的三位一体找矿模式为间接寻找穆呼锰矿提供依据,对以后的地质找矿提供一定的参考。

In order to study the extension of manganese ore bodies and target ore belts,a 1:2000 IP ladder profile measurement and a 1:10,000 IP ladder profile measurement were carried out in the work area.The study summarizes the"high-amplitude frequency(greater than 3%),medium-low resistivity(about 250Ω.m),weak magnetic negative anomaly(between-100nT and 100nT)".The Trinity prospecting model provides a basis for indirect search for Muhu manganese ore.For the future geological prospecting to provide a certain reference.
