Re: How is 'bog iron' formed? - MadSci
Chemically, the soluble form of iron is often iron (II) carbonate. When water accumulates in bogs and marshes, evaporation causes loss of the carbonate as CO 2 and the hydrated oxide, limonite forms. The formula of limonite is: Fe 2 O 3.3H 2 O Iron-oxidizing bacteria are bacteria that can accumulate iron(II) and oxidise it to iron (III).

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.
