Description
Ferromagnetic minerals such as magnetite carry a remanent magnetization only at temperatures below the Curie Point, but at higher temperatures they are paramagnetic. In a volcanic rock and when cooling below the Curie Point, crystals acquire a remanent magnetization that is anti-parallel to the magnetic field at its location. This magnetization is called thermoremanent magnetization.
