    Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C ...

    Magnetite and hematite are oxides of iron. Magnetite occurs as a trace to minor mineral in several kinds of meteorites. Rubin (1997a) states that it is the "principal oxide phase in the CK chondrites," a rare type of meteorite (0.3%). Geiger and Bischoff (1995) found that the modal abundance of magnetite ranged from 1% to 8% in the 19 CK ...

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.

    Hematitic sand and sandstones are mainly consisting of quartz but these quartz grains have an intense pink, orange or red color. The coloring agent in this sand is volumetrically insignificant – it is hematite (oxide of iron) that forms very thin rust-colored pigment on larger silicate grains.. However, its influence on the appearance of sand or sandstone is very strong.
