Bog iron

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 made from bog ore will often contain residual silicates, which can form a glassy coating that imparts some resistance to rusting.
