Abstract
Electrical resistivity investigation was carried out around Adudu and its environ, part of Akiri sheet 232, Middle Benue Trough, Central Nigeria, in order to study the subsurface geologic layer with a view of determining the depth to the aquifer and thickness of the geoeelectric layers. Vertical Electrical Sounding (VES) using Schlumberger array was carried out at seventeen (17) VES stations with the aid of ABEM tetrameter (SAS 300) for data acquisition. The field data obtained have been analysed using computer software (WinResist) which gives an automatic interpretation of the apparent resistivity. The VES results revealed heterogeneous nature of the subsurface geological sequence. The geologic sequence beneath the study area is composed of hard pan top soil (clayey and sandy-lateritic), weathered layer, partly weathered or fractured basement and fresh basement. The resistivity value.. View More»
