are used to measure the variations of the earth's gravity field and thus to get important data to model the earth's crustal structure.
is used by oil and mineral prospectors to measure the density of the subsurface, effectively the rate of change of rock properties.
are used to determine the natural radioactivity (gamma radiation) of near-surface rocks and soils. The measurements reveal information on rock and soil properties, particularly their contents of natural radionuclides. Natural radionuclides are mainly the three elements Potassium, Uranium and Thorium
are used to determine the Earth's magnetic field and its anomalies. Since crustal rocks show different magnetisations, magnetic measurements can reveal information on the crustal structure
