Bog iron occurs in swamps and bogs that contains dissolved ferrous iron. The ferrous iron is then oxidized by iron bacteria ( Thiobacillus ferrooxidans and Leptospirillum ferrooxidans) which used ferrous iron as energy source (chemolithotrophy). It causes oxidation of ferrous iron and precipitation as ferrix iron.
