Palaeomagnetism is the study of the Earth’s magnetic field preserved in rocks, sediment, or archeological materials. Some minerals, at the time of their formation, can become magnetized parallel to the Earth’s magnetic field.

Palaeomagnetism has a range of applications. Paleomagnetic evidence, both reversals and polar wandering data, was instrumental in verifying the theories of continental drift and plate tectonics. Paleomagnetic evidence combined with geochronological methods are used in dating rocks and in reconstructing the deformational histories of the earth’s crust and to estimate the age of sites bearing fossils. Conversely, for a fossil of known age, the paleomagnetic data can fix the latitude at which the fossil was laid down.
