GEOPHYSICAL INVESTIGATION OF A FAULT ZONE–CASE HISTORY FROM ILE‐IFE, SOUTHWEST NIGERIA*

A fault zone, inferred as a major linear structure from aerial photographs of the University of Ife Campus, has been investigated. Results of a multi-method geophysical survey indicate that the zone is characterized by relatively low resistivity and high magnetic effect. They are characteristic of a sheared and perhaps saturated fault zone with magnetic mineral infillings along its plane. The near symmetry of the magnetic anomalies over the fault zone may not be indicative of a step faulting. The geoelectric sections show no indication of any significant displacement. The above supports results of a previous study that the fault is a strike-slip fault.
