Abstract
Geoelectric investigations of litho-facies changes in Ewekoro limestone were carried out using Schlumberger vertical electrical sounding technique to delineate the vertical and lateral limestone deposit based on maximum current electrode separation of 1.0 km. The data was interpreted using conventional partial curve-matching method and computer iteration technique. The surface lithology was composed of lateritic topsoil, clayey sand, sandstone, sand, clay/shale, limestone with sand, and fresh limestone with different litho-facies. Limestone distributions of different litho-facies, thickness from 15.1 and 89.8 m and resistivity values ranging from 10.4 to 100.0 kΩ-m were identified in sixty locations.
