Paleomagnetic dating[ edit ] A sequence of paleomagnetic poles usually called virtual geomagnetic poleswhich are already well defined in age, constitutes an apparent polar wander path APWP.

For paleomagnetic earth dating methods us, it is suggested to use the APWP in order to date a pole obtained from rocks or sediments of unknown age by linking the paleopole to the nearest point on the APWP. Two methods of paleomagnetic dating have been suggested: 1 the angular method and 2 the rotation method. The polarity timescale has been previously determined by dating of seafloor magnetic anomalies, radiometrically dating volcanic rocks within magnetostratigraphic sections, and astronomically dating magnetostratigraphic sections.

Uranium–thorium. Potassium–argon. Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale. Nature has conveniently provided us with radioactive nuclides that have half-​lives which range.
