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?

  • Pressure estimates based on metamorphic mineral assemblages across most of the major shear zones do not show measurable vertical displacements within the uncertainty of the geobarometers.

    “However, pressure estimates based on metamorphic mineral assemblages across most of the major shear zones do not show measurable vertical displacements within the uncertainty ( + 1 kbar or about _+ 3 kin) of the geobarometers”
  • The boundary between the Central Metasedimentary and Central Gneiss Belt shows metamorphic pressures apparently increasing over a short distance from about 6 kbar in the Bancroft domain to about 8 kbar in the eastern Central Gneiss Belt.

    “except for the boundary between the Central Metasedimentary and Central Gneiss Belt (Fig. 2) where metamorphic pressures apparently increase over a short distance from about 6 kbar in the Bancroft domain to about 8 kbar in the eastern Central Gneiss Belt.”

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.
