| dc.description.abstract | The spectral analysis of the magnetic anomalies over some part of Central Benue Trough, Nigeria, has been carried out in order to determine the magnetic source depths and the variability of basement structures. The aeromagnetic maps of the study area was digitized at two kilometer (2km) intervals and were subjected to multi-regression-least-squares analysis in order to obtain the residual field values. Two- dimensional (2-D) spectral analyses were then carried out to determine the average magnetic source depths. The results of the analysis reveal that the thickness of the sedimentary cover in the area varies between 1.25km and 5.60km; and 0.13km and 1.53km for deeper and shallower sources respectively. The results of this study are indicative of the basement overlain being irregular in shape and is associated with faulted structures | en_US |
