However, sophisticated 3D survey equipment are very expensive. In this study, a singlechannel ABEM SAS 300B Terrameter was used to obtain 3D models of the subsurface. This survey was carried out at three different locations within Abeokuta, a basement complex terrain of southwestern Nigeria. The area falls within longitudes 3.

A manual 4-electrode system was used in the Electrical Resistivity Tomography survey at the three locations.
Use of PROSYS software for data display & filtering - field measurements on test site: handling of wires, electrodes, role of ground resistance, safety rules. Interpretation of resistivity images: - use of 2D/3D inversion for depth interpretation - examples of applications in various geological areas. Maintenance of equipment. Software for resistivity and 3D IP inversion. Zondres3d program is designeed for three-dimensional interpretation of electrical tomography resistivity and induced polarization data in land, cross-borehole and marine variants. Electrical tomography is a whole technique including the method of field observations and.
Each location was marked into 7 by 7 square grids with 1 m, 3 m and 5 m unit electrode spacings in succession. The pole-pole array was used with the two remote electrodes placed at distances of 23 m, 40 m and 65 m from the grids of 1 m, 3 m and 5 m unit electrode spacings respectively, to reduce their telluric effects on the measured apparent resistivity values. To reduce survey time consumption, the cross-diagonal survey method was adopted. The data obtained were analysed using a 3D inversion software called RES3DINV and 3-Dimensional models of the subsurface were also generated using Slicer Dicer graphics software. The study revealed layers extending to depths of 7.75 m, 23.2 m and 38.7 m for unit electrode spacings of 1 m, 3 m and 5 m respectively. It revealed resistivity values ranging from 7.3 Ωm to 300 Ωm for electrode spacing of 1.0 m; 13.8 Ωm to 200 Ωm for electrode spacing of 3 m and 3.9 Ωm to 200 Ωm for electrode spacing of 5 m at the first location. At the second location, it revealed resistivity values ranging from 0.53 Ωm to 120.0 Ωm for electrode spacing of 3 m and 0.30 Ωm to 100 Ωm for electrode spacing of 5 m.
