dc.description.abstractThe geophysical electrical resistivity method of Schlumberger Vertical Electrical Sounding (VES) was carried out within the premises of the University of Ilorin, along each traverse near some selected high-rise buildings on the University campus. The study was aimed at mapping the subsurface geologic features such as rock layering, lithological types, and sequence in the subsurface that may pose danger to the existing structures. A total of fourteen (14) VES stations were established with a maximum current electrode separation of 200m and inter-VES spacing of 20m. VES geo-electric equivalent layers range from three (3) to five (5) layers within the area. Geoelectric 2D sections further confirmed that the area is characterized by layer series of topsoil, laterite, sandy clay, weathered/fractured basement, and fresh basement. The resistivity distribution (60-300 Ωm) around profile 1 in the vicinity of the Faculty of Arts terminates at about 20 m depth. This is attributable to the incompetent footing. The subsurface features and overburden materials delineated in profile 5 close to the postgraduate students’ hostel are most favorable to civil engineering constructions as the ranges of resistivity distributions (200-2000 Ωm) are attributable to competent footing for the superstructures.en_US
