Earth and Mars

Sulfuric acid produced during the oxidation of acid sulfate soils strips iron from the soil and toxic amounts of the colourless iron can then be washed into waterways. The colourless iron in the acid water changes to rust red when it contacts less acid water, such as rainwater or seawater. This results in a rust coloured iron oxide scum known as Floc which can smother vegetation and strain concrete and soil.
