Abstract:
This study presents a comprehensive geophysical analysis of the Bamenda Massif, Southeastern Nigeria, using high-resolution aeromagnetic and Landsat data to interpret subsurface geological structures and identify potential zones of mineralization. The area, part of the Nigerian Basement Complex, was analyzed using Oasis Montaj, ArcGIS, and Erdas imaging software for data enhancement, anomaly extraction, and modeling. Regional-residual separation techniques and reduction-to-pole transformations were applied to magnetic data to isolate shallow and deep-seated anomalies. Quantitative interpretations involved Peters’ length, Sokolov, and slope methods to estimate depths to magnetic source bodies, yielding depths ranging from 0.1 km to over 1.1 km. Magnetic susceptibility values ranged from 0.0022 to 0.0049 c.g.s., correlating well with inferred intrusive bodies such as dykes and magnetized quartzites. Landsat-derived lineament maps further revealed cross-cutting fracture systems and structural trends influencing mineralization.
