Exploration geophysics is the applied branch of geophysics which uses surface methods to measure the physical properties of the subsurface Earth, along with the anomalies in these properties, in order to detect or infer the presence and position of ore minerals, hydrocarbons, geothermal reservoirs, groundwater reservoirs, and other geological structures.

The common unit of gravity measurement in exploration geophysics is milliGal (1,000 mGal = 1 Gal = 1 cm/s 2 = 0.01 m/s 2). These units refer to acceleration due to gravity, and the average value at the earth surface is around 980,000 mGal or 9.8 m/s 2. By comparison, anomalies in mineral and oil exploration seldom exceed a few hundred milliGals.
