The Road to becoming a Ore Mineral Master

Magnetite
Chemical Formula Fe2+Fe3+2O4
Mohs Hardness 5.5-6
Specific gravity 5.2
Description Magnetite is a highly magnetic ore mineral that is one of the three common naturally-occurring oxides of iron.

Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields.

The relationships between magnetite and other iron-rich oxide minerals such as ilmenite, hematite, and ulvospinel have been much studied; the reactions between these minerals and oxygen influence how and when magnetite preserves a record of the Earth's magnetic field.
