Geoelectric mapping for basement structures and its hydrogeologic implications at Lafe area, Akure, Southwestern Nigeria

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.
