Previous studies in the Lower Benue Trough using magnetic data with low resolution obtained by Geological Survey of Nigeria (GSN) in 1974, were centered on the mapping of major intrusive structures, fault systems, stratigraphy, sediment thickness, spatial distribution of igneous intrusions, and delineation of depo-centres (Oha et al., 2016; Ofoegbu, 1984; Ofoegbu and Mohan, 1990).	cache/esrj-105868.pdf	txt/esrj-105868.txt
