| 摘 要： | 通过河南郁山隐伏铝土矿详查中的应用实例,结合覆盖区矿区勘查特点,对可控源音频大地电磁法（CSAMT）在测量隐伏铝土矿勘查中的作用进行了总结。河南郁山隐伏铝土矿勘查深度为150～700 m,常规的直流电测深法很难在勘查深度上满足需要。而基于CSAMT的WINGLINK2D和WINGLINK1D反演结果,能准确反映深部含矿岩系、地层及构造的特征,为合理优化工程布置打下了良好的基础。

| Abstract: | Combining the application of this method in the exploration of the Yushan large-size concealed bauxite deposit in Henan Province and the exploration characteristics of the covered mining area,this paper discusses the advantage of CSAMT for the pre-survey and survey of concealed bauxite deposits.The exploration depth of the Yushan concealed bauxite deposit in Henan Province is generally 150～700 m,which is so deep that the conventional D.C.electric sounding method cannot meet the needs.The Controlled Source Audio-frequency Magnetotellurics(CSAMT) is a new geophysical technique,and has such advantages as stronger signal,deeper exploration depth and higher resolution.Based on the inversion result of WINGLINK2D and WINGLINK1D,it can accurately reflect the characteristics of deep ore-bearing rock series,formations and structures,and optimize the layout of the project. |
