Background intervals are characterized by light δ34S values (average -6.0 ± 0.6‰) that display relatively high fractionations of 30-40‰ from Cambrian seawater (ca. +30‰), indicating that microbial sulfate reduction was not impeded in these intervals.
“Background intervals are characterized by light δ34S values (average -6.0 ± 0.6‰) that display relatively high fractionations of 30–40‰ (30) from Cambrian seawater (ca. +30‰; ref. 31), indicating that microbial sulfate reduction was not impeded in these intervals (32).”

“A phosphoric acid-dolomite fractionation factor of 1.01066 (Rosenbaum and Sheppard, 1986) was used for oxygen isotope calculations (this introduces uncertainties of up to 2xfor d18O because the evolved CO2 is likely to derive from a mixture of dolomite, structurally substituted carbonate in the…”

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.
