| dc.description.abstract | This paper presents a geophysical study for ground water evaluation in a typical crystalline basement complex terrain of Camic garden estate in Ilorin metropolis, North central basement complex of Nigeria. Very Low Frequency-Electromagnetic (VLF-EM) and Ground Magnetics (GM) were used for structural evaluation/delineation combined with Electrical Resistivity Method (ERM) using the Vertical Electrical Sounding (VES) Technique. Eight (8) VLF-EM and GM profiles covering a distance range of 70 to 300 m were established, VLF-EM at a measuring intervals of 10 m each, while six (6) VES were carried out based on quantitative, semi-quantitative of the VLF-EM and GM, a correlation was also carried out between the VLF-EM and the GM results of conductive zones and zones of low magnetic susceptibility that may be diagnostic of fault, fracture/weathered material. The six (6) VES were carried out using Schlumberger configuration, with AB/2 varying from 1.00 m to 225.00 m, with the predominant curve being of the HA type representing three-layer earth model i.e. the top soil, the clayey/weathered layer, and the fresh basement for most of the curves obtained, the clayey/weathered layer constitutes the major auriferous unit in the area, and are characterised by moderately low resistivity value which ranged between 23.00 and 200.00 Ωm while the thickness varies 13.2 to 61.0 m. The study reveals that 83% of the study area may be of low water bearing/yield owing to the thick clayey column that characterised the weathered layer without fractured basement. Therefore, there is a critical need for elaborate ground water study in the entire area, to be able to site boreholes with a reasonable yield in an environment where fractured basement/bedrock is rare to find. | |
