Application of Different Electrode Array in Delineating Cassiterite Bearing Layer for A Two-Dimensional Tomography Survey Within Pingel Village of Bauchi State

Abstract

Electrical resistivity method consist of various arrays that had been successfully applied in mineral explorations. Three important  electrode arrays in 2D imaging surveys were tested in this study by creating a tomography of the subsurface to determine which array is  the most successful in defining the cassiterite bearing layer. These arrays are Wenner, Schlumberger and Dipole - dipole. The numerical modeling was created through vertical fracture zone and correlated with a representative lithology of the area produced by using tape to  measure depths to different lithology at an exposed mining pit. The results showed that the Schlumberger is the most suitable electrode  array that can resolve both vertical and horizontal structures present in the subsurface. It was also obvious that the Schlumberger is a better array that images the vertical and horizontal contacts and represented these geological structures more accurately than the  Wenner and Dipole-dipole arrays.
