Abstract

This work focuses on the use of aeromagnetic data to delineate potential mineralization zones within the Yola Arm, Upper Benue Trough, northeast, Nigeria. The area exhibits a complex geological framework, where igneous and sedimentary formations interact along various fault structures. In this study, the Total Magnetic Intensity (TMI), Reduction to the Equator (RTE), Residual, First Vertical Derivative (FVD), Analytic Signal, Horizontal Gradient Magnitude (HGM), and Tilt Derivative maps were analyzed to delineate mineralization zones and analyze structural trends. The results reveal prominent high-intensity magnetic anomalies around northern and southeastern sections of the study region, indicative of magnetite-rich bodies and igneous intrusions. Structural trends extracted from lineament and rose diagram analyses highlight major NW-SE and N-S orientations with subsidiary NE-SW orientations, corresponding to regional fault systems and fracture zones. Superimposition of lineaments on the Analytic Signal map demonstrates strong correlations between tectonic features and zones of high magnetic susceptibility, confirming the structural control on mineralization.
