Geophysical techniques work through applying one of several types of force to the ground, to measure the resulting energy with use of geophysical equipment and infer the geology from this. Geophysics is generally much quicker than the aforementioned methods, however, requires more data processing (officebased work) to develop the geological ...

Historically, geophysical technique (magnetic) was first used in Sweden in the 17th century for prospecting iron ore (Reedman, 1979). Geophysical techniques gained more acceptability in the early 1923 (Gupter, 1986) because of exploration for crude oil. Relevance of Geophysics across the world is as a result of oil and solid mineral exploration.

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
