Abstract
The quest for mineral exploration, search for water, and pre-construction surveys have become so prevalent in our society today. Structures that host some of the minerals are found in or within the striatal components of layers. The geo-electrical investigation involving the electrical resistivity method was carried out within the premises of Federal University Wukari to generate the surface and subsurface geologic information that was used in determining the stratigraphic sequence in the study area. Eleven (11) vertical electrical sounding points were conducted. The data obtained were interpreted by the computer iteration process. This was done to observe the variability in a layered structure concerning resistivity. Analysis of result reveals that layer one has a resistivity range from 48.96?m-9374.4?m, layer two has 47.32?m-721.7?m, layer three 0.573?m787.76?m, layer four has 0.034?m-3172?m, and layer five has 0.487?m-6914.9?m. they corresponding thickness ranges from 0.28m-4.89m, 0.424m-15.05m, 1.04m-30.5m and 2.18m-33.56m respectively. The analysis also reveals four to five lithological units comprising top lateritic soil, sandstone, silt, sandy shale, shale, and intercalation of clay-shaley materials.
