Paleomagnetism refers to the study of the record of the Earth's magnetic field preserved in various rocks and minerals through time.
The study of paleomagnetism is possible because iron-bearing minerals such as magnetite may record past directions of the Earth's magnetic field when the rocks containing them were formed or last heated up.
Paleomagnetic signatures in rocks can be recorded by three different mechanisms:-
- First, iron-titanium oxide minerals in basalt and other igneous rocks may preserve the direction of the Earth's magnetic field when the rocks cool through the "Curie temperature" for those minerals. (The Curie temperature of magnetite, is about 580°C).
- In a completely different process, magnetic grains in sediments may align with the magnetic field during or soon after deposition.
- In a third process, magnetic grains may be deposited from a circulating solution, or be formed during chemical reactions, and may record the direction of the magnetic field at the time of the mineral's formation.

What is the mythological origin of the word geology?
Geology = study of the Earth - from geo- (Earth) and -ology (study of) 'Gaia, 'land' or 'earth', from the Ancient Greek Gæa or Gea is the primal Greek goddess personifying the Earth. Gaia is a primordial and chronic deity in the Ancient Greek pantheon and considered a Mother Goddess or Great Goddess.

What is the name for someone who studies ancient bones?
Lots of professions study ancient bones. Within archaeology there are osteoarchaeologists who study human remains and zooarchaeologists (or archaeozooologists) who study animal remains. Both these fields have alternative names depending on the particular aims of the research or the location of the researcher. For example people who study human remains may also be known as physical anthropologists or bioarchaeologists. Paleontologists also may study ancient bones which have been fossilized.
What do you mean by magnetic?
Terrestrial magnetism is the study of magnetic field on earth.
