The Examination of Biogenic and Non-Biogenic Iron Precipitates Created by Hydrogen Sulphide

Original language description

Metabolism of sulphate-reducing bacteria (SRB) generally consists of organic substrates or molecular H2 oxidation and sulphates reduction under anaerobic conditions. By oxidizing low molecular weight organic compounds (e.g. lactate, acetate) they obtainenergy and nutrients. Biological-chemical process based on the ability and activity of these bacteria to reduce sulphates results in hydrogen sulphide creation which binds with metal cations in solutions to insoluble precipitate forms. In anoxic sedimentary environment with iron redundancy the amorphous iron sulphide is often the initial sulphide phase to be formed and exhibits poor crystallinity in the form of small crystal sizes and short-range crystal order. Although many studies have focused on themineralogy and surface chemistry of the more crystalline and more thermodynamically stable sulphides such as pyrite and pyrrhotite, an understanding of the crystal habit and surface chemistry of the more poorly crystalline Fe sulphides is
