摘要
在马家疃金矿产勘查中,由于地层中的含石墨黑云片岩具有低阻高极化率特征,加之金矿体埋藏较深,限制了电法勘查手段的应用范围。采用可控源音频大地电磁测深(CSAMT)法,可以在垂深电阻率反演断面图上圈出低电阻率异常,后经钻探工程验证,该异常很好的反映矿体的空间分布范围。
        In the exploration of Majiatuan gold deposit, the application of electrical prospecting method is limited because of the low resistivity and high polarizability of graphite-bearing biotite schist in stratum and the deep burial of gold orebody.Using CSAMT method, low resistivity anomaly can be circled on vertical resistivity inversion cross-sectional map. After verification by drilling engineering, the anomaly can well reflect the spatial distribution of ore body.
