Abstract

Structural features of Ikogosi Warm Spring and its environs have been delineated using qualitative and quantitative interpretation methods. Euler-Deconvolution and local wave number methods were adopted for quantitative and qualitative interpretation of aeromagnetic data sheet 243 by Geological Survey Agency of Nigeria (GSN) in 2008, respectively. Euler solution revealed depth range of -2.98 to -290 m to the magnetic sources, while local wave number method revealed depths to magnetic sources/basements ranging from -2.1 to -1311.4 m of the geologic lineaments in Ikogosi Warm Spring and its environs. Both methods revealed outcrop features characterized by their positive depth values above the mean ground level. Both methods proved efficient way of resolving shallow magnetic source depth giving a very plausible depth of -2.1 m for local wave number and -2.98 m for Euler solution in the area of study.
