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. Early history of seismic technique

Geophysical surveys generally look for concentrations of anomalously high values of the property being measured. The results of the survey are used to identify a target of interest, or to correlate the spatial variation of values of the property with variations in the geology. Thus the primary reasons to do geophysics are to get information on geology, and possibly to find targets of economic ...

Mississippi Valley-type base-metal deposits are difficult geophysical targets and direct detection of the ore is not usually possible. However, gravity and magnetic data can be used to locate basement highs associated with such deposits and, on a semi-regional scale, induced polarisation surveys have been used to locate marcasite halos associated with the orebodies. Volcanic-hosted massive ...
