Abstract

Electrical resistivity method was used in carrying out geophysical investigations at the Centre for Energy Research and Training (CERT), Ahmadu Bello University, Zaria, with a view of determining the depth to the bedrock, thickness of the top soil and weathered basement.Vertical Electrical Sounding (VES) using Schlumberger array was carried out at forty (40) VES stations. ABEM terrameter (SAS 300) was used for the data acquisition. The field data obtained have been analysed using computer software (IPI2win) which gives an automatic interpretation of the apparent resistivity. Results from the interpretation suggest three layers in most parts of the study area. However, there is a case of two layers at a station. The resistivity value for the topsoil layer varies from 2 to 738Ωm with thickness ranging from 1 to 3.9 metres. The weathered basement has resistivity values ranging from 32 to 1735Ωm and thickness of between 0.52 and 23 metres. The fresh basement (bedrock) has resistivity values ranging from 100 to 6,036Ωm.
