Formation of diagenetic siderite in modern ferruginous,

We infer early diagenetic growth of siderite crystals as a response to sedimentary organic carbon degradation and the accumulation of dissolved inorganic carbon in pore waters. We suggest that siderite formation proceeds through syntaxial growth on preexisting siderite crystals, or possibly through aging of precursor carbonate green rust. Crystal growth ultimately leads to spar-sized (>50 μm,Hydrothermal and resedimented origins of the precursor,,Inga Köhler, Kurt O Konhauser, Dominic Papineau, Andrey Bekker, Andreas Kappler, Biological carbon precursor to diagenetic siderite with spherical structures in iron formations, Nature Communications, 10.1038/ncomms2770, 4, 1, (2013).Biological Carbon Precursor to Diagenetic Siderite With,,Biological Carbon Precursor to Diagenetic Siderite With Spherical Structures in Iron Formations _ Nature Communications _ Nature Publishing Group - Free download as PDF File (.pdf), Text File (.txt) or read online for free.
