This book titled "Analysis of Aeromagnetic data over Jalingo and Environs NE Nigeria" tend to address issues regarding to geophysical exploration from which many benefits would be driven. From the beginning, potentials for secondary mineralization were critically analyzed from magnetic data, depth from where magnetic response in the area was evaluated given hope for petroleum exploration in this area. Potentials for an alternative source for power generation considered, from the results obtained the area seems to be viable. In view of that an aeromagnetic data can provide an information about an area even where there is no record of Mineralization, thickness of sedimentary over lay which can support hydrocarbon potential as while as where there is no record of heat flow and geothermal gradient.
