Abstract: The depth to top of limestone body within a concession at Ibese, in Ogun state, Southwestern Nigeria was evaluated using the Vertical Electric Sounding (VES). The electrical resistivity method employing the VES technique was used to carry out the geophysical investigation and a total 10 VES data was acquired. Three curve types were identified from the acquired data which are the H, A and HK-type curves. Also a geo-electric section was obtained from the result of the field sounding areas, where all the materials above the limestone is regarded as an overburden. The study area (line) spans 5 km of which the trend (direction) of the limestone was found to be NW-SE. VES locations 2, 5, 6, 7, 8 were found to have a shallow depth which is less than 6 m and can be said to be of economic importance.
