摘要

Lizhuangzhai concealed bauxite deposit in western Henan Province is found with the Controllable Source Audio-Frequency Magnetotelluric Prospecting Measurement method. By using this way, a series of rolling Cagniard low resistivity belts (bodies) were found. The drilling has verified that the deposit has the same distribution character with Ordovician roof fossil erosion surface; therefore indicate the target prediction of the concealed bauxite deposit. The author summarized the geophysics features of the Lizhuangzhai deposit and inductive the prospecting criteria of the concealed bauxite deposit in this area.
