Bog iron - Wikipedia

Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO(OH)).. Iron-bearing groundwater typically emerges as a spring oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface.
