Down-hole Geophysics in Mineral Exporation |

17-10-2019· Geophysical surveys provide information about the physical properties of rocks, such as their density, magnetic properties or electrical conductivity. Explorers undertake geophysical surveys from the air using a plane or helicopter, or from the ground using an array of sensors and vehicles on land, or by sending geophysical probes down a drill hole.

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
