%X In this study, we performed some filters to highlight geological structures and/or features which are found in the igneous rocks, between the latitudes 9<span style=\"white-space:nowrap;\">¡ã</span>45'N to 10<span style=\"white-space:nowrap;\">¡ã</span>45'N and longitudes 13<span style=\"white-space:nowrap;\">¡ã</span>15'E to 14<span style=\"white-space:nowrap;\">¡ã</span>30'E. The application of the first vertical derivative (FVD) and the horizontal gradient magnitude (HGM) on a total magnetic data over the study area has led to put in evidence: 1) geological features as geological boundaries, faults, dykes, folds on the FVD map; 2) abundant aeromagnetic lineaments probably fractures, dykes and contacts, ex-hibit a conjugate relationship suggesting a near NE and NW tectonic trends; 3) existence of a possible prominent near E-W compression, characterized by a possible dextral displacement of geological formations by the shear movements; 4) and the magnetic signature of the country rocks.
