Mineral potentials satellite imagery Nasarawa and Environs



The investigations involve the analyses of high resolution aeromagnetic data and satellite imagery over parts of Nasarawa and environs. Airborne magnetic data and satellite imagery were interpreted to delineate structures and lineament pattern of the study area as potential for minerals occurrence, field work was undertaken in the study area to relate the effect of the structures in field to result obtained from the interpretation of the high resolution aeromagnetic data. The lineaments identified on both aeromagnetic map and Satellite imagery are in agreement with the main structural trend of the Benue Trough. Results from the interpretations indicate anomaly trends in the NE-SW, NW-SE, E-W, and NNE-SSW directions. The rose diagrams obtained from the magnetic residual map and the satellite imagery suggest predominantly NE-SW, NW-SE directions, the consistency in the alignment of lineaments suggests a possible genetic association of these anomalies. The occurrences of lineaments which include pegmatites, fracture, faults joints veins and fold as revealed in the quantitative analysis of the magnetic residual contour map, satellite imagery and field work excercise show the interplay of tectonic activities due to multiple deformational episodes, this study highlight magnetic lineaments as key indicators to mineral occurrence.
