Paleomagnetism a level
WebA standard approach in paleomagnetism is to calculate the equivalent geocentric (but not axial) dipole that would give rise to the observed site-level paleodirection. The pole position of this equivalent dipole is known as a ‘virtual geomagnetic pole’ or VGP, and, under the assumption of a geocentric dipole, is independent of the site location. WebWhat is paleomagnetism? The liquid inner core convected as it's hot, which produces a magnetic field. How does the earth produce it's own magnetic field? When lava erupts, it …
