Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Low molecular mass aromatics (≤C16) predominate over high molecular mass PAHs (>C16), and nonalkylated parent PAHs are more abundant than alkylated PAHs in the AIDP samples and in previous Archean reports.

    “Like the PAHs and diamondoids that previous studies reported in Archean rock extracts and hydropyrolysates (3,21,24,28), the low molecular mass aromatics (≤C 16 ) predominate over high molecular mass PAHs (>C 16 ), and nonalkylated parent PAHs are in greater abundance compared with alkylated PAH (SI Appendix, Figs.S4 and S5 and Tables S8 and S10).”

    From Reappraisal of hydrocarbon biomarkers in Archean rocks (2015) · cites this paper as [28]

  • Extractable PAHs could be syngenetic but heavily altered by reactions between hydrothermal fluids and bitumen, but this mechanism may not account for the full >10‰ 13C enrichment.

    “Lastly, the extractable PAHs could be syngenetic but heavily altered by reactions between hydrothermal fluids and the bitumen (28), but this mechanism may not be able to account for the full >10‰ 13 C enrichment.”

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.
