Paleomagnetism - Wikipedia, the free encyclopedia
Paleomagnetism is the study of the record of the Earth's magnetic field preserved in various magnetic minerals through time. The study of paleomagnetism has demonstrated that the Earth's magnetic fie...

Geomagnetic reversal - Wikipedia, the free encyclopedia
Source
A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged. These events often involve an extend...

"It represents an excellent effort...and is probably the most up-to-date work available on Earth's magnetic field....The specific terms used are well explained and the mathematics are not overwhelming. ... The discovery of geomagnetic field reversals has been one of the most significant findings of paleomagnetism.

The Earth's magnetic north pole can change in orientation (from north to south and south to north), and has many times over the millions of years that this planet has existed. The term that refers to changes in the Earth's magnetic field in the past is paleomagnetism.

Considering that ships, planes and Boy Scouts steer by it, Earth's magnetic field is less reliable than you'd think. Rocks in an ancient lava flow in Oregon suggest that for a brief erratic span about 16 million years ago magnetic north shifted as much as 6 degrees per day.

Literally 'ancient magnetism', paleomagnetism is the study of the signals left in volcanic and sedimentary rocks by the Earth's magnetic field; signals which can be preserved over millions of years of geological time.
