Was There Really an Archean Phosphate Crisis?
Abstract
During the Archean, massive amounts of iron were deposited in the form of banded iron formations. It has been suggested that sedimenting particles of ferric oxyhydroxide may have stripped dissolved phosphate from the oceans, causing a reduction in phytoplankton productivity. However, that model does not take into account the high concentration of dissolved silica that was present in seawater at that time. We show experimentally that silica effectively competes with phosphate for sorption sites on ferrihydrite particles. Furthermore, coprecipitation of silica with ferrihydrite reduces particle reactivity toward phosphate. Hence, Archean oceans probably contained considerably more phosphate than previously predicted.

“However, the iron formation data have recently been linked to high dissolved silica concentrations rather than a P crisis; silica can outcompete P for binding sites on iron oxides (Konhauser et al., 2007; Planavsky et al., 2010).”

In the citing paper
“As iron-and silica-rich chemical sedimentary deposits, IF have proven useful because the trace metal content in the least metamorphosed units are almost entirely derived from seawater (see Bjerrum and Canfield, 2002;Konhauser et al., 2007;2009;2015;Robbins et al., 2013).”

“As these partitioning scenarios are sensitive to matrix effects, such as different Si concentrations (e.g., Konhauser et al. (2007Konhauser et al. ( , 2009) ) and the presence of additional cations, (Jones et al. (2015), see also section 4.1), they cannot be directly equated.”

In the citing paper
“Konhauser et al. (2007) demonstrated that a high silica ocean would have attenuated phosphate adsorption to precipitating Fe oxyhydroxides, thereby keeping P in solution while still accounting for low P/Fe ratios in IF (Fig. 4) -and casting doubt on the idea of an Archean P crisis.”

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.
