Hematite - Wikipedia

Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on earth, and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.
