INTEGRATION AND JUXTAPOSITION OF EULER AND WERNER DECONVOLUTION TECHNIQUES FOR LITHO-STRUCTURAL CONTACT IDENTIFICATION AND MAGNETIC BASEMENT DEPTH DETERMINATION: A CASE STUDY OF ADO-EKITI, SOUTH-WEST NIGERIA

The study applied high-resolution aeromagnetic data for the characterization and consequent delineation of geological structures of Ado-Ekiti (sheet 244) and its environs in southwestern Nigeria. The principle of tensor Euler deconvolution was harnessed for the interpretation. The acquired data were processed using Excel package and Geosft Oasis Montaj 8.4v to model the subsurface topography. Euler Deconvolution (ED) showed the minimum depth of 132.2m and maximum depth of 2233.9m for shallow and deep magnetic sources, Werner Deconvolution (WD) were used to confirm magnetic anomalies and corresponding intrusive contacts like dykes and sills. The output from Euler deconvolution was associated with dykes with deeper depth range of 132.2 beneath mean sea level. This study has therefore proven that the integration of Euler and Werner deconvolution techniques on the aeromagnetic data is valuable in the characterization of the subsurface geological structures delineation/ contact identification of most of the encountered structures in the area.
