ABSTRACT

The experimental approach of two-dimensional (2D) geoelectrical resistivity imaging in which the resistivity is allowed to vary both laterally along and vertically beneath the survey line but constant in the perpendicular direction was carried out for mineral exploration. A series of 2D apparent resistivity data were generated in a parallel and perpendicular direction using dipole-dipole electrode configuration engaging the SAS 1000 ABEM terrameter. 2.5m electrode separations (interline spacing) in the study area was adopted. The 2D data sets were collated and inverted separately using RES2DINV software producing 2D model for each line. These survey locations were observed to be composed of lateritic soil, sand, sandstone, shale, limestone, clay, dolomite with resistivity values ranging between 259Wm to 2159Wm for the unit electrode spacing adopted.
