Abstract :

The aeromagnetic data have been used to re-evaluate parts of the Upper Benue Trough, Nigeria using spectral analysis technique in order to appraise the mineral accumulation potential of the area. The regional field was separated with a first order polynomial using Polyfit program. The residual data was subdivided into 24 spectral blocks using OASIS MONTAJ software program. Two prominent magnetic depth source layers were identified. The deeper source depth values obtained ranges from 1.56 km to 2.92 km with an average depth of 2.37 km as the magnetic basement depth; while for the shallower sources, the depth values ranges from -1.17 km to 0.98 km with an average depth of 0.55 km. The shallow depth source is attributed to the volcanic rocks that intruded the sedimentary formation and this could possibly be responsible for the mineralization found in parts of the study area.
