Paleomagnetism (or Palaeomagnetism in the United Kingdom) is the study of the record of the Earth`s magnetic field in rocks, sediment, or archeological materials. Certain minerals in rocks lock-in a record of the direction and intensity of the magnetic field when they form. This record provides information on the past behavior of Earth`s magneti.....
Paleomagnetism is the magnetism that remains in volcanic rock from the time it solidified from magma. 
1. The fixed orientation of a rock's crystals, based on the Earth's magnetic field at the time of the rock's formation, that remains constant even when the magnetic field changes. 2. The study of such phenomena as indicators of the Earth's magnetic history.
The study of Earth's magnetic field over time. When rocks that contain magnetic minerals are deposit
The study of ancient magnetic fields, as preserved in the magnetic properties of rocks. It includes studies of changes in the position of the magnetic poles and reversals of the magnetic poles in the geologic past.
Study of the Earth's past magnetism as it is recorded in the rocks.
The science of the reconstruction of the Earth's ancient magnetic field and the positions of the continents from the evidence of remnant magnetization in ancient rocks.
