Keywords: Electrical resistivity tomography, fault lines, lithology, seismic station.
2D electrical resistivity tomography was carried out at Ile-Ife seismographic station, Osun state Nigeria with the aim of investigating the geological structures beneath the station in order to identify areas of anomalous resistivity are related to fractures or fault lines and also determine the lithologies of the subsurface. The survey was carried out with Terrameter SAS 1000 and ES 464 electrode selector equipment. Dipole-dipole configuration at electrode spacing of 2 m was used to acquire the data. The result showed that the station is underlain by three layers; overburden composed of lateritic clay, clayey sand, the weathered and fresh basement. Fault lines and fractured zones were not observed in all profiles. The result was also compared with bedrock quality grades, which further inferred best sites for seismic station based on the lithology of the area.
