ABSTRACT
The research work was channeled towards the subsurface of Uniben and environs in order to investigate for minerals. The wenner alpha electrode configuration was deplored throughout in this study. Two profiles were covered; each profile 50 metres apart. One transverse lines were in the North –South direction and the other in the West –East direction.
To obtain a good 2-D picture of the subsurface, the coverage of the measurements must be 2-D as well. The first step was to make all possible measurements with electrode spacing of 10 metres. For this system with 21 electrodes, there are 18 possible measurements. Another sequence of measurements with 20 metres electrode spacing was made, and there were 15 possible measurements. The sequence of measurement was carried out for 30, 40, 50, and 60 metres spacings. The procedure was followed in all the two traverses where this experiment was undertaken. The distance between adjacent traverse is 50 metres. The data from each 2-D survey line was initially inverted independently with RES2DINV Inverse for Windows version 4.01 (KIGAM 2001) to give 2-D cross-sections. A pseudo section conveys a qualitative two- dimensional resistivity variation with depth within the subsurface.
