摘要：
The geoelectric mapping of Lafe area, was carried out using electrical resistivity and very low frequency electromagnetic (VLF-EM) methods. The geoelectric parameters allowed the delineation of four major subsurface layers the sandy clay/clayey sand/laterite top soil, the clay layer, the weathered/fractured basement and the presumably fresh bedrock. The result also yielded information on the structural disposition of the bedrock, bedrock ridges/depsressions, orientation and thickness of the fractures.
