Global analysis of aqueous alteration products on the Martian surface suggests a predominance of juvenile or weakly modified minerals.
“Indeed, global analysis of aqueous alteration products on the Martian surface suggests a predominance of juvenile or weakly modified minerals (Tosca & Knoll 2009).”

The flows responsible for eroding the late Noachian and Hesperian surface were relatively short-lived.
“This suggests that the flows responsible for eroding the late Noachian and Hesperian surface were relatively short-lived.”

A successful theory for surface warming must yield valley network erosion rates consistent with the geologic evidence but avoid extensive surface carbonate formation and aqueous alteration of sediments.
“A successful theory for surface warming must yield valley network erosion rates consistent with the geologic evidence (Hoke, Hynek & Tucker 2011) but avoid extensive surface carbonate formation and aqueous alteration of sediments (Tosca & Knoll 2009; Ehlmann et al. 2011).”

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.
