Geophysical Methods of Exploration

The most commonly used first step in geophysical exploration process is the aeromagnetic survey. A magnetometer or often a series of magnetometers are attached to an aircraft in a stinger, or wingtip pods to measure the intensity of the earth's magnetic field, thereby permitting the detection of magnetic anomalies caused by the minerals that are present in the ground.
