Paleomagnetism (Paperback)

High Quality Content by WIKIPEDIA articles! Paleomagnetism is the study of the record of the Earth's magnetic field preserved in various magnetic minerals through time. The study of paleomagnetism has demonstrated that the Earth's magnetic field varies substantially in both orientation and intensity through time.A paleomagnetist is a scientist who studies the ancient magnetic field by measuring the magnetic direction recorded in minerals in rocks and sediments, acquired at the time of their formation (remanent magnetization), then using methods similar to geomagnetism to determine what configuration of the Earth's magnetic field may have resulted in the observed orientation.
