Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Mineralogical Classification : Magnetite-Hematite-Martite

Martite is a psuedomorph of Hematite after Magnetite, not a weathering product. Therefore it is a chemical replacement of the Magnetite by Hematite, produced at depth and under pressure. It may be either a straight replacement process or an oxidation like process, but without depth and pressure the shape and form of the Magnetite would be lost.
