Abstract

Iron-rich (ferruginous) conditions were a prevalent feature of the ocean throughout much of Earth's history.The nature of elemental cycling in such settings is poorly understood, however, thus hampering reconstruction of paleoenvironmental conditions during key periods in Earth evolution.This is particularly true regarding controls on nutrient bioavailability, which is intimately linked to Earth's oxygenation history.Elemental scavenging during precipitation of iron minerals exerts a major control on nutrient cycling in ferruginous basins, and the predictable nature of removal processes provides a mechanism for reconstructing ancient ocean chemistry.Such reconstructions depend, however, on precise knowledge of the iron minerals formed in the water column.Here, we combine mineralogical and geochemical analyses to demonstrate formation of the mixed-valence iron mineral, green rust, in ferruginous Lake Matano, Indonesia.Carbonated green rust (GR1), along with signifi cant amounts of magnetite, forms below the chemocline via the reduction of ferrihydrite.Further, we show that uptake of dissolved nickel, a key micronutrient required for methanogenesis, is signifi cantly enhanced during green rust formation, suggesting a major control on methane production in ancient ferruginous settings.

  • Ferrous iron sorption to Fe(III)-silica particles may have given rise to 'green rust'-type deposits that eventually transformed into magnetite or iron silicates.

    “Ferrous iron sorption to those particles may also have given rise to 'green rust'-type deposits that eventually transformed into magnetite or iron silicates (Tamaura et al., 1984; Zegeye et al., 2012; Halevy et al., 2017).”
  • Green-rust can be found within a naturally stratified water column and may act as an important transitory phase between the redoxcline and the export of iron phases to the sediment.

    “Zegeye et al. (2012) demonstrated that green-rust can be found within a naturally stratified water column, and that it may act as an important transitory phase between the redoxcline and the export of iron phases to the sediment.”
  • Carbonated green-rust has been observed in modern ferruginous and sulfate-poor Lake Matano in Indonesia.

    “Carbonated green-rust has been observed in modern ferruginous and sulfate-poor Lake Matano in Indonesia (Zegeye et al., 2012)”
  • Studies in Lake Matano show that green rust may play an important role in scavenging Ni from ferruginous water columns.

    “Studies in the ferruginous ocean analogue Lake Matano, Indonesia, have shown that green rust may play an important role in scavenging Ni from ferruginous water columns”

  • Production of trace hydrogen sulfide through microbial sulfate reduction may strongly govern aqueous Ni concentrations even under ferruginous conditions.

    “Further, production of trace hydrogen sulfide through microbial sulfate reduction may play a strong role in governing aqueous Ni concentrations, even under ferruginous conditions”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
