Exploration geophysics  Wikipedia
Exploration geophysics Wikipedia

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 useful geological
