可控源音频大地电磁法在立洼峡地区铅锌矿找矿中的应用

The application of Controlled Source Audio-frequency Magnetotelluric technology of Pb-Zn ore explosions in Liwaxia area

通过立洼峡地区铅锌矿区勘查找矿应用实例,结合勘查区特点,对可控源音频大地电磁法(CSAMT)在寻找隐伏铅锌矿中的作用进行了总结.认为CSAMT在寻找隐伏铅锌矿中发挥了间接找矿作用;而基于DF1线和DF2线的反演结果,能较准确反映深部含矿地层及构造特征,为钻探工程布置提供了良好的基础资料.

By using Controlled Source Audio-frequency Magnetotelluric Technology （CSAMT） in Liwaxia Pb-Zn ore for prospecting, the role of CSAMT was summarized in searching hidden Pb-Zn ore combined with characteristics of exploration area. It is considered that CSAMT play an indirect role in search hidden Pb-Zn ore. The inversion of DF1 and DF2 can accurately reflect deep ore-bearing stratum and structural features. CSAMT could contribute to drilling arrangement by providing better basic information.
