ABSTRACT
The urgent need to prospect or search for clay deposits in University of Benin, Benin City, South-South Nigeria, geophysically became imperative in view of the fact that clay as one of the natural resources aid the general economy by setting up industry/factory where the citizen of the area can be gainfully employed and hence combating crime rate in the area.
The science of prospecting for clay deposits in the area actually entailed carrying out an electrical resistivity survey method employing Wenner array configuration. Electrode separation of (a) = 10m, 20m, 30m, 40m, 50m, 60m for each profile line was obtained. The total length of investigation was taken as 200m. The 2D data sets were inverted separately using RES2DINV software producing 2D model for each line.
The result of the geophysical survey showed low resistivity range of 4-120Ωm,indicating the presence of clay deposit at depths of approximately 2m, with thicknesses approximately 5m between point 22.5m and 27.5m, at a depth of approximately 6m and a thickness of approximately 50m between point 37.5m and 87.5m and at a depth of approximately 2.3m and a thickness of approximately 5m between point 115m and 120m.
