dc.description.abstractThe research site is the whole landmass of the Federal College of Education, Zaria, seated on the basement complex of north-central Nigeria. Direct current resistivity geophysical method was employed to characterize parameters such as the basement depth and topography, aquifer depth and thickness, weathered basement distribution as well as mapping of orientations of fractures and faults present in the premises using the radial sounding technique. The conventional vertical electrical sounding (VES) Schlumberger array was carried out at 40 stations, eight of which were radial stations. Radial sounding was used to establish resistivity anisotropy which gives clue for the choice of consistent VES profile direction used throughout the fieldwork. Results from the resistivity interpretation suggest three layers in most parts of the premises with some minor occurrence of two and four layers. The first layer (topsoil) has a thickness ranging between 3.5 and 14.0 m; the second layer (weathered basement) thickness ranges between 9.0 and 36.5 m, while the third layer (fresh basement) is deepest (40.1 m) towards the eastern corner of the area. The aquifer depth ranges from 1.5 to 4.0 m with a thickness range of 5.0 to 14.0 m. The thickest aquifer occurs around the center to the west of the area. Results from radial sounding show the presence of resistivity anisotropy, an insight into fracturing and faulting; this is more pronounced around the west-central part of the premisesen_US
