Resistivity Survey of the Western Part of Plataeu State Polytechnic Permanent Site, Barkin Ladi, Nigeria

Abstract

A geoelectrical resistivity investigation, using Schlumberger vertical electrical sound (VES) was conducted in the western part of the permanent site of the Plateau State Polytechnic Barkin Ladi. Jos. The purpose of survey was to determine electrically the structure of layers, their thickness, their relative positions, and depth under the surface. Sixty-six VES were carried out over an area extent of 1.0km by 0.5km. The result indicated three, four, five, and six layering structure. The thickness of the horizon overlying the basement range from 1.5m to 37.2m. Typical geologic sections of the area consist of red laterite, sticky clay, sandy clay, highly weathered, weathered and fairly weathered granites. The weathered granite and sandy clay horizons are considered in this study as water bearing horizons.
