Between 1.9 and 1.8 Gya there was an apparent return to deposition of massive shallow-water iron formations, with iron oxidation occurring in the wave-mixed upper portion of the oceans.
“Most notably, between 1.9 and 1.8 Gya (Fralick et al. 2002) there was an apparent return to the deposition of massive shallow-water iron formations, with iron oxidation occurring in the wave-mixed upper portion of the oceans (Dimroth & Chauvel 1973, Planavsky et al. 2009, Raye et al. 2015).”

Some ca. 1.88 Ga Gunflint-type microfossils from the Animikie Basin have been reinterpreted as chemolithoautotrophic Fe(II)-oxidisers.
“some of the ca. 1.88 Ga Gunflint-type microfossils from the Animikie Basin have been reinterpreted as chemolithoautotrophic Fe(II)-oxidisers (Golubic and Lee, 1999; Planavsky et al., 2009).”

Deposition of late Palaeoproterozoic IF at ca. 1.88 Ga occurred in basins having varied redox conditions and a strong redoxcline separating an upper oxic water column from deeper waters that were suboxic to anoxic.
“This interpretation implies deposition of late Palaeoproterozoic IF at ca. 1.88 Ga in basins having varied redox conditions and a strong redoxcline separating an upper oxic water column from deeper waters that were suboxic to anoxic (Planavsky et al., 2009)”

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.
