Geomagnetic stratigraphic dating

Therefore, the magnetic north pole is at approximately an 11 degree angle from the geographic north pole.

This is possible because volcanic flows acquire a thermoremanent magnetization and sediments acquire a depositional remanent magnetization, both of which reflect the direction of the Earth's field at the time of formation.After World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating.Magnetism occurs whenever electrically charged particles are in motion.The Earth's magnetic north pole can change in orientation (from north to south and south to north), and has many times over the millions of years that this planet has existed.The term that refers to changes in the Earth's magnetic field in the past is paleomagnetism.
