Authigenic Carbonate and the History of the Global Carbon Cycle
Open accessAbstract
The Third Way: Because organic carbon contains a larger fraction of the light isotope 12 C than inorganic carbonate, variations in the carbon isotopic record of sedimentary rocks are thought to represent changes in the amount of organic carbon buried as sediments (and thus removed from the rest of the carbon cycle). Schrag et al. (p. 540 ; see the Perspective by Canfield and Kump ) suggest that historically a third component was important: authigenic carbonate. Authigenic carbonate is not produced in any appreciable quantity today, but was much more abundant when the level of atmospheric oxygen was low.

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.
