    Application of Aeromagnetic and Remotely Sensed Data in Mineral Exploration in Parts of Ife-North, Osun State, Southwestern Nigeria
    (Department of Chemical Engineering, University of Benin, Benin City, Nigeria, 2022-12) Osisanya, O.W.; Shaibu, O.B.; Abolarin, O.M.; Eyankware, M.O.; Okpala, E.C.
    This paper analysed aeromagnetic data over parts of the Ilesa schist belt of Nigeria with a view to assessing the sub surface structural settings that might favour mineralisation in the study area using aeromagnetic data and satellite remote sensing imageries. The subsurface lineaments were detected and traced out from the maxima of horizontal gradient magnitude, peaks of analytical signal magnitude. The structural trends of the composite lineament map show predominant lineament directions; NE-SW, NNE-SSW, E-W, and NW-SE. These trends were in agreement with the major regional tectonic trends of Southwestern Nigeria. The interpretation of the aeromagnetic dataset gave an insight into the regional geology and structural trends of the area. The derived lineaments may serve as a reference for future geological and structural mapping. Based on the information gathered so far, the study area shows potential for presence of both primary and alluvial/eluvial gold deposits.
