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?

  • Hopane and sterane concentrations in the RHDH2A sample are more compatible with concentrations reported in earlier Archean biomarker studies of the Mount Bruce and Transvaal supergroups.

    “Furthermore, the hopane and sterane concentrations measured in our analysis of the RHDH2A sample are more compatible with the concentrations reported in earlier Archean biomarker studies of the Mount Bruce and Transvaal supergroups (7,21)”

    From Reappraisal of hydrocarbon biomarkers in Archean rocks (2015) · cites this paper as [21]

  • Detectable hopane and sterane concentrations in the AIDP samples were about one to three orders of magnitude lower than those reported in earlier Archean biomarker studies.

    “For comparison, the hopane and sterane concentrations that were detectable and measured in the AIDP samples are approximately one to three orders of magnitude less than the hopane and sterane concentrations reported in earlier Archean biomarker studies (7,21).”

    From Reappraisal of hydrocarbon biomarkers in Archean rocks (2015) · cites this paper as [21]

  • Based on extractable PAHs, the MPI-1 parameter gives calculated vitrinite reflectances between 2.63% and 3.00%.

    “Based on extractable PAHs, the MPI-1 parameter yields calculated vitrinite reflectances (R c ) between 2.63-3.00%(SI Appendix, Table S9) (21,35)”

    From Reappraisal of hydrocarbon biomarkers in Archean rocks (2015) · cites this paper as [21]

  • According to H/C ratios and other thermal history indicators, the metamorphic grades of AIDP-2 and AIDP-3 are similar to or lower than those of rocks from which biomarkers were previously reported.

    “According to currently available H/C ratios and other indicators of thermal history, the metamorphic grades of AIDP-2 and AIDP-3 are similar to (1-4, 6, 7, 15, 21, 26) or lower than (5,22,23) the metamorphic grades of the rocks from which biomarkers have been previously reported.”

  • 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).”

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.
