Introduction to Potential Fields: Gravity

thumbnail image of printed fact sheet

Gravity and magnetic exploration, also referred to as “potential fields” exploration, is used to give geoscientists an indirect way to “see” beneath the Earth’s surface by sensing different physical properties of rocks (density and magnetization, respectively). Gravity and magnetic exploration can help locate faults, mineral or petroleum resources, and ground-water reservoirs. Potential-field surveys are relatively inexpensive and can quickly cover large areas of ground.
