Application of Electrical Resistivity in Delineating Depth of Auriferous Veins in Parts of Minna, North-Central Nigeria: Implication for Gold Exploration
Author(s): Wallace Ogor*
Gold for its high resistance to chemical reaction, high conductivity and ductility, and its rarity has been one of the most sought-after commodities for at least 7000 years and geophysical techniques (gravity, magnetics and electrical methods) have been widely used to get subsurface information of the Earth, without engaging in invasive digging. The geophysical evaluation of gold mineralization potential in parts of Minna has been carried out using three (3) principal geophysical techniques; Vertical Electrical Sounding (VES), Horizontal Resistivity Profiling (HRP), and Electrical Resistivity Tomography (ERT), with Schlumberger, Wenner and dipole-dipole electrode configuration respectively. These result of the analysis of the data obtained revealed a resistivity variation ranging from 20-75 Ωm in different parts of the study area. Also, it indicates a mineralized body that is di..
