ABSTRACT

A geophysical investigation was carried out in parts of Oye-Ekiti, to delineate and characterize the response of simulated mineral target in the area. Induced polarization (IP) and electrical resistivity (2D) were employed in this study. This research used a model tank experiment to stimulate, measure, and analyze data acquisition. The interpretation was carried out using Dipro software and statistical techniques to assess the accuracy of the pole configuration in defining mineral zones. The IP data revealed a number of subsurface zones with high real component current density which define the potential subsurface structural features (fractures/ faults zones) with possible kaolinite zone. The results from the geo-electric imaging models reveal a heterogeneous nature of mineralisation within zone of high resistivity (low conductivity) that may represent kaolin bearing quartzite vein. The 2D section of the kaolinated showed regions of both high and low conductivity with values that ranged from -100 to 74.9 Ω-1m-1 with structural trends in the NE-SW direction. The results from this research will serve as a future reference for other researchers who may wish to embark on a similar research in the mineralized zone and also help enlighten mining investors on the mineral potentials of the area.
