Investigation of Low-Resistivity Regimes of the South-Central Portion of Gidan Kwano (Phase II), Federal University of Technology, Minna, Nigeria

Abstract

A chiefly standardised, set-piece, and academic approach was used to interpret the result of a 4 km2 vertical electrical sounding survey at the New Development Phase II, Gidan Kwano Campus, Federal University of Technology, Minna, Nigeria. The constraints imposed by this approach restricted the conclusion that was drawn regarding aquifer prospect to a segment of the southeast and a couple of points in the mid-plane of the area of study as identified by their georeferenced co-ordinates in the eponymous interpretation of the 4 km2 vertical electrical sounding survey report. However, the area with the greatest data-density fidelity is the portion characterised by consistently low-resistivity values at depths. An examination of this portion from the perspective of the “Geoexplore Empirical Standardisation for Minna Area” makes it clear that it was possible to observe such very low resistivity values at depths of 40 m through 70 m because fracturing of the original fresh basement rock owing to some disturbance in the past would have allowed accumulation of groundwater in the resulting fractures of the buried rock-mass. This observation liberalises the constraint placed on the advisory that it is inappropriate to explore beyond 34 m in the core area of study of this work and other works in the suite.
