Paleomagnetism facts

Paleomagnetism (occasionally palaeomagnetism ) is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists. Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic … See more As early as the 18th century, it was noticed that compass needles deviated near strongly magnetized outcrops. In 1797, Von Humboldt attributed this magnetization to lightning strikes (and lightning strikes do … See more Paleomagnetism is studied on a number of scales: • Geomagnetic secular variation is the small-scale changes in the direction and intensity of the Earth's magnetic field. The magnetic north pole is constantly shifting relative to the axis … See more Paleomagnetic evidence, both reversals and polar wandering data, was instrumental in verifying the theories of continental drift and … See more • Butler, Robert F.
