Article Title: Geophysical Properties of Sub Surface Lithologies at Ekpoma Area of Edo State, Nigeria
by Ezomo F.O and Aiyohuyin, E.O

The urgent need to prospect for subsurface lithologies or rock types geophysically in Ekpoma Area of Edo State, Nigeria became imperative so as to aid industrialization that will further create job opportunities for the citizen of the area. This will assist to improve the economy of the state in particular and Nigeria in general based on the world exploration assignment. The research work was carried out by using Vertical Electrical Sounding (VES) employing Schlumberger array of electrical resistivity method. The array employed a minimum current electrode spread of 500m and a maximum spread of 1000m to justify the geophysical survey operation. The results of the geophysical survey operation indicated the following lithologies: clays, shales, sandstones, limestones, sands, having resistivities varying from about 40 ohm-m -to 60,000 ohm - m. Their depths varied from about 0.4m to while their thicknesses varied from 0.4m to 220.0m. Area of vital subsurface lithologies e.g. clay have been identified for future drilling operation.
