Deposition of banded iron formations by anoxygenic phototrophic Fe(II)-oxidizing bacteria

Kappler, Andreas, Pasquero, Claudia, Konhauser, Kurt O., Newman, Dianne K.·2005·Geology

Abstract

The mechanism of banded iron formation (BIF) deposition is controversial, but classically has been interpreted to reflect ferrous iron [Fe(II)] oxidation by molecular oxygen after cyanobacteria evolved on Earth. Anoxygenic photoautotrophic bacteria can also catalyze Fe(II) oxidation under anoxic conditions. Calculations based on experimentally determined Fe(II) oxidation rates by these organisms under light regimes representative of ocean water at depths of a few hundred meters suggest that, even in the presence of cyanobacteria, anoxygenic phototrophs living beneath a wind-mixed surface layer provide the most likely explanation for BIF deposition in a stratified ancient ocean and the absence of Fe in Precambrian surface waters.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The consensus amongst workers is that the precursor phase during sedimentation of IF was most likely Fe(III)-oxyhydroxides or an Fe(III)-Si gel.

    “Despite the consensus amongst workers that the precursor phase during the sedimentation of IF was most likely Fe(III)-oxyhydroxides (e.g., Konhauser et al., 2002; Kappler et al., 2005; Posth et al., 2014; Sun et al., 2015) or an Fe(III)-Si gel (e.g., Percak-Dennett et al., 2011; Zheng et al., 2016)”
  • At a conservative, experiment-based, depth-integrated, phototrophic Fe(II)-oxidation rate of 1.4 × 10^-5 M/day (corresponding to a depth of 100 m), an estimated Fe(II) concentration of 0.5 mM, and the modern global mean eddy-diffusion rate of 0.1 cm2/s, a photoferrotrophic bacterial layer 17.6 m thick was required to completely oxidise the Fe(II) input.

    “At a conservative, experiment-based, depth-integrated, phototrophic Fe(II)-oxidation rate of 1.4 × 10 -5 M/day (corresponding to a depth of 100 m), an estimated Fe(II) concentration of 0.5 mM, and the modern global mean eddy-diffusion rate of 0.1 cm 2 /s, it was estimated that a photoferrotrophic bacterial layer 17.6 m thick was required to completely oxidise the Fe(II) input.”
  • These estimates are significantly larger than the 17.6 m thickness calculated with eddy-diffusion alone by Kappler et al. (2005).

    “These estimates are significantly larger than the 17.6 m thickness calculated with eddydiffusion alone by Kappler et al. (2005).”
  • Numerical models have been used to suggest that anoxygenic photosynthesisers would control Fe(II) oxidation even if the surface layer was weakly oxygenated.

    “Numerical models have been used to suggest that anoxygenic photosynthesisers would control Fe(II) oxidation even if the surface layer was weakly oxygenated (Kappler et al., 2005).”

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.
