Two-billion-year-old evaporites capture Earth’s great oxidation
Open accessAbstract
A strongly oxidizing Paleoproterozoic era: Two billion years ago, marine sulfate concentrations were around one-third as high as modern ones, constituting an oxidizing capacity equivalent to more than 20% of that of the modern ocean-atmosphere system. Blättler et al. found this by analyzing a remarkable evaporite succession more than 1 billion years older than the oldest comparable deposit discovered to date. These quantitative results, for a time when only more qualitative information was previously available, provide a constraint on the magnitude and timing of early Earth's response to the Great Oxidation Event 2.3 billion years ago.

Stable calcium isotope composition of Tulomozero evaporites, together with presence of magnesium sulfate minerals, constrains contemporaneous seawater to contain at least approximately 10 mmol kg-1.
“The stable calcium isotope composition of Tulomozero evaporites, together with the presence of magnesium sulfate minerals, further constrains contemporaneous seawater to contain at least ∼10 mmol kg -1 (Blättler et al. 2018).”

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.
