ABSTRACT Geochemical data indicate that protons released during pyrite (FeS 2 ) oxidation are important drivers of mineral weathering in oxic and anoxic zones of many aquatic environments, including those beneath glaciers. Oxidation of FeS 2 under oxic, circumneutral conditions proceeds through the...
