Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. It is most often used to detect or infer the presence and position of economically ...

high concentrations of magnetite, potentially as sources for iron ore. To help visualise the distribution of values, colour is employed. In geophysical displays, deep blues denote the lowest values, while reds and purples identify the highest readings. A scale bar is usually included to show the range of values.

Geophysical exploration using measurements of the earth's magnetic field was employed earlier than any other geophysical technique. von Werde located deposits of ore by mapping variations in the magnetic field in 1843. In 1879, Thalen published the first geophysical manuscript entitled The Examination of Iron Ore Deposits by Magnetic Measurements.

The major geophysical method utilised in gold exploration is high-resolution aeromagnetics which is used to map favourable structures and rock types. Electrical and electromagnetic methods can also be used where gold is associated with sulphides. Geophysics has been comparatively little used in exploration for iron ore.

This is made particularly difficult by the wide range of densities of Fe ores that can lead to the association of both positive and negative gravity anomalies with Fe ore bodies. The end result is that the amount and quality of information interpreted from the results of gravity surveying is a direct function of the auxiliary geological information available either through geological or other ...
