Magnetic survey | geophysics | Britannica

A magnetometer is a device that measures magnetic field or magnetic dipole moment.Some magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.Other magnetometers measure the magnetic dipole moment of a ...

Apr 09, 2015· Seismic survey determines the quality of bedrock and can locate the contact surface of geological layers, or of a compact mineral deposit in the ground. In case of iron ores, the detailed magnetic study of anomalous areas may involve using a magnetometer in a helicopter, or ground surveys employing hand-held or other portable magnetometers.

Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital. Besides, metal ores can be magnetic as well as electrically conductive, whereas high density of host rocks or limited deposit volume may leave ore deposits without clear gravity signatures. Figure 5.
