2D ELECTRICAL RESISTIVITY TOMOGRAPHY FOR THE ASSESSMENT OF MINERALS’ OCCURRENCES IN UGONEKI, EDO STATE, SOUTH-SOUTH, NIGERIA

Geophysical investigation using the 2D Electrical Resistivity Tomography (ERT) was carried out to assess subsurface of Ugoneki and its environs in order investigate for minerals. A total six (6) traverses, 200 m long each, three (3) transverse lines were North-South direction other traverses West-East Wenner electrode configuration. resistivity data acquired along each traverse. The inverted reveal a spatially continuous distribution within study area. results depth 39.6 across values vary from 87.1 – 3423 Ωm entire From standard table, following solid non-metallic type minerals can be delineated area which is representative sandy clay, lateritic clay sand, sandstone limestone with that range 89.9 Ωm, 1201 1462 2069 respectively. implication this research know particular location where these are located future exploration. compared those literature found good agreement. In quantify minerals, it also recommended use higher dimension (3D) method
