Hematite (or haematite) Hematite is the most important ore mineral of iron. It is an oxide mineral and is found in a variety of colours, with red, orange and brown occurring when the iron in hematite begins to rust. There are also several forms of hematite, some of which are: kidney ore, a massive, botryoidal (lumpy) or reniform (kidney shaped) form; specularite, a micaceous (flaky) form ...

Hematite is a common mineral in soils. It is often inherited from the parent materials but is also formed pedogenically in soils in warm regions. It occurs in Mediterranean soils, soils of warm deserts, and in many strongly weathered tropical soils. There is evidence that hematite is very slowly replaced by goethite in cool humid regions.

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 forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

While it was recently reported that the conduction band of iron minerals can mediate electron transfer between Fe(II) and different Fe(III) lattice sites during Fe(II)-catalyzed mineral transformation, it is unclear whether such a conduction band mediation pathway occurs in the microbial Fe(II) oxidation system under dark and anoxic subsurface conditions. Here, using cytochrome c (c-Cyts) as a ...
