Hematite - Wikipedia

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).

Limonite, or brown ore, is to be found at the bottom of some bogs and shallow lakes, in favorable situations, where the weathering rocks have yielded iron to the water draining into these basins. The limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of years, as at Radnor Forges, Quebec. Considerable deposits of limonite have been found in

Iron-Oxide Concretions and Nodules, 1 | Some

Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people's attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
