Foreword: Ferrosic hydroxides, green rusts and fougerite in the biogeochemical cycle of iron. Speciation of iron, characterisation and structure of green rusts and Fe II-III hydroxycarbonate fougerite. Green rusts synthesis by coprecipitation of FeII-FeIII ions and mass-balance diagram. Synthesis of green rusts by oxydation of Fe(OH)2, their products of oxidation and reduction of ferric oxyhydroxides, Eh-pH Pourbaix diagrams. Bioreduction of ferric species and biogenesis of green rusts in soils. Geochemical and microbiological controls on dissimilatory iron reduction. Microbial reduction of iron in smectites. Green rusts in electrochemical and microbially influenced corrosion of steel. Iron oxides: from molecular clusters to solid. A nice example of chemical versatility.
