Gravity & Magnetic Geology

Gravity and magnetic approaches are directly related to the physical qualities of rocks, such as density and susceptibility, and are extremely valuable for field geologists and geophysicists in mapping and identifying diverse rock types. They're also employed to find minerals with a lot of density and susceptibility contrast as compared to country rock. Geophysical approaches based on gravity and magnetic fields are both passive. They seek out naturally occurring fluctuations in the earth's gravity and magnetic fields rather than relying on controlled sources. As a result, some military applications of these surveys have included the silent detection of submarines and hazardous unexploded ordnance for a long time. Mineral magnetism has experienced a surge of scientific achievements in recent years, ranging from theoretical results to more practical experiments. Magnetic measurements and imaging provide unique and useful data for a variety of geosciences and planetary science applications, including tectonics, paleoclimate and paleoenvironmental study, studies of the Earth's deep interior, and planetary surface and interior exploration.
