Abstract :This study investigates the relationship among the various types of rock within the basement complex region and their possible yield in term of groundwater productivity. Four different rock types were considered at various locations in Akure metropolis. Electrical resistivity method was adopted using Horizontal Profiling utilizing Wenner array as well as Vertical Electrical Sounding (VES) technique using Schlumberger configuration. The Horizontal Profiling technique was used to determine areas characterized by structural features associated with weak zones that may be diagnostics of cracks, joints, fractures or highly weathered geologic material, while VES was used as a follow up to identified weak zones as a confirmatory test as well as delineation of layer stratification and geologic materials associated with layer parameters that maybe applicable for groundwater occurrence. The results derived from geoelectric parameters were used to determine the second order parameters (Dar-zarouk) for groundwater productivity modeling. The finding reflects the various yield capacity of the different rock types that were considered for this study and without prejudice to fracture/thick weathered basement.Keywords : Ceofficient of Anisotropy, Rock Types, Groundwater Yield, Longitudinal Conductance, Transverse Resstance
