Limonite - Wikipedia
Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH) n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and

Hematite - Wikipedia
Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe 2 O 3 and has been widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral latt 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).

earthy hematite and martite (locally magnetite with minor goethite (q.v.), chert, mica, and chlorite). Hard ores are dense, firm aggregates of magnetite, martite, compact hematite, and specularite. Hematite also forms microscopic grains in ores as replacements of minnesotaite, stilpnomelane, grunerite, and chlorite (Mann, 1953).

Limonite mineral Britannica
The name limonite properly should be restricted to impure hydrated iron oxide (with variable water content) that is colloidal, or amorphous, in character. Often brown and earthy, it is formed by alteration of other iron minerals, such as the hydration of hematite or the oxidation and hydration of siderite or pyrite.
