The first step in providing evidence for continental drift from paleomagnetism is to determine the paleomagnetic poles for two or more continents. To determine the location of such poles, oriented samples are collected from several horizons within a formation and at several different localities. See more To determine the pole of spreading by the first method, it is necessary to know the location for each continent of two or more paleomagnetic poles whose age is … See more This method produces only an approximate location for a spreading pole. To determine the pole of spreading by this method, it is necessary to know the location … See more Once the spreading pole is known, the continents may be rotated around this pole until the paleomagnetic pole for one time period for one continent matches the … See more
WebMar 25, 2014 · This was originally coined a "continental drift." Note that Scotland and England were actually separated by the Ocean before the Silurian (Fig. 2a). ... WebIn the 1950s, paleomagnetic evidence supporting continental drift became available. When rock is in a molten state, the magnetic particles it contains are free to move around, and they orient themselves toward the Earth's magnetic poles. Once the rock cools and hardens, the orientation of the individual magnetic particles becomes fixed.
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 field at the time they formed. This record provides information on the past behavior of the geomagnetic …
