Abstract

High-resolution geochemical analyses of organic-rich shale and carbonate through the 2500 million-year-old Mount McRae Shale in the Hamersley Basin of northwestern Australia record changes in both the oxidation state of the surface ocean and the atmospheric composition. The Mount McRae record of sulfur isotopes captures the widespread and possibly permanent activation of the oxidative sulfur cycle for perhaps the first time in Earth's history. The correlation of the time-series sulfur isotope signals in northwestern Australia with equivalent strata from South Africa suggests that changes in the exogenic sulfur cycle recorded in marine sediments were global in scope and were linked to atmospheric evolution. The data suggest that oxygenation of the surface ocean preceded pervasive and persistent atmospheric oxygenation by 50 million years or more.

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

  • Concentration spikes at 2.5 to 2.66 Ga ago in Mo, Se, and Re and isotopic excursions of Mo, Se, U, and N have been interpreted as arising from O2 transients or "whiffs" of O2.

    “Concentration spikes at 2.5 to 2.66 Ga ago in Mo, Se, and Re and isotopic excursions of Mo, Se, U, and N have been interpreted as arising from O2 transients or “whiffs” of O2 (110–113).”

  • Pyrite in the S-MIF interval carries distinct S-MIF signals, with Δ33S reaching as high as +8‰ and Δ36S/Δ33S ratios centering around −0.98, characteristic of the Neoarchean array.

    “The pyrite in the S-MIF interval (below the pink band in Fig. 2) carries distinct S-MIF signals, with Δ33S reaching as high as +8‰ and the Δ36S/Δ33S ratios centering around −0.98, which is characteristic of the Neoarchean array (Fig. 3) (30, 43).”
  • The Δ36S/Δ33S slope of −0.9 is widespread in Neoarchean sedimentary rocks and interpreted to be of atmospheric origin.

    “This is also supported by the Δ36S/Δ33S slope of −0.9, which is widespread in Neoarchean sedimentary rocks and interpreted to be of atmospheric origin (9, 25, 30, 43).”

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.
