In a mining area in Northwest China, the induced polarization method and magnetotelluric method are used for joint exploration. The same set of equipment collects data at the same time and at the same points, so as to improve the acquisition efficiency, and complete large depth + shallow high-resolution exploration at the same time. The induced polarization method has very high resolution in the shallow part, and can obtain the full waveform polarizability data, which can clearly reflect the underground electrical characteristics within 600m; The deep exploration by magnetotelluric method reflects the deep rock mass and structural characteristics. Combined with the shallow IP section, the underground electrical structure can be inferred more comprehensively.
Construction method:TDIP bilateral three pole,50m point distance;MT vector measurement, 200m track distance.
