In this paper, the authors used such geophysical exploration methods as the high-precision geomagnetic method, the resistivity profiling method and the induced polarization method to synthetically study the exhausted areas of the Archean sedimentary metamorphic iron mines in eastern Hebei, built an effective geophysical exploration combination model for the exhausted areas, and summarized the serviceability and validity of various geophysical exploration methods in the exploration of exhausted areas under different geological settings.
