8.8: Paleomagnetic Evidence for Plate Tectonics

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 WebFeb 4, 2024 · Later on, in the 1960s new evidence from paleomagnetism was presented and, with this new evidence, the geologists’ community finally accepted Wegener’s continental drift theory.

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.
