Ground Magnetics: applications

---

Magnetics are used to understand the general structure of underlying rock by identifying faults and folds otherwise hidden beneath the surface. 

Magnetics are used to discover and evaluate the size and shape of ore bodies by mapping the magnetism of underlying rocks.

Magnetics are used to define deposits:

Iron ore, gold, copper, zinc, nickel, diamonds, chromite, manganese, asbestos.

Magnetics are used to determine depth to basement rocks and to locate and define the extent of sedimentary basins.

Magnetics are used to identify demagnetised rocks produced by the heat of geothermal activity; potential epithermal gold deposits.
