Potential Fields

Potential Fields Course


VIDL Network experience can introduce you to Potential Fields, or more specifically, gravity and magnetics. Magnetic data are a little more complicated to use since the magnetic field is dipolar. This means that a magnetized body’s signature (anomaly) character has a minimum and a maximum, and it changes shape based on its geographic relation to the earth’s magnetic field. The initial measured fields must therefore be corrected for geographic location. Once the magnetic field is corrected, the interpretation of geologic structures becomes simpler because their signatures (anomalies) relate to the size, shape, depth, and magnetic susceptibility of the various bodies.
