Abstract

Here, we explore enrichments in paleomarine Zn as recorded by authigenic iron oxides including Precambrian iron formations, ironstones, and Phanerozoic hydrothermal exhalites. This compilation of new and literature-based iron formation analyses track dissolved Zn abundances and constrain the magnitude of the marine reservoir over geological time. Overall, the iron formation record is characterized by a fairly static range in Zn/Fe ratios throughout the Precambrian, consistent with the shale record (Scott et al., 2013, Nature Geoscience, 6, 125-128). When hypothetical partitioning scenarios are applied to this record, paleomarine Zn concentrations within about an order of magnitude of modern are indicated. We couple this examination with new chemical speciation models to interpret the iron formation record. We present two scenarios: first, under all but the most sulfidic conditions and with Zn-binding organic ligand concentrations similar to modern oceans, the amount of bioavailable Zn remained relatively unchanged through time. Late proliferation of Zn in eukaryotic metallomes has previously been linked to marine Zn biolimitation, but under this scenario the expansion in eukaryotic Zn metallomes may be better linked to biologically intrinsic evolutionary factors. In this case, zinc's geochemical and biological evolution may be decoupled and viewed as a function of increasing need for genome regulation and diversification of Zn-binding transcription factors. In the second scenario, we consider Archean organic ligand complexation in such excess that it may render Zn bioavailability low. However, this is dependent on Zn-organic ligand complexes not being bioavailable, which remains unclear. In this case, although bioavailability may be low, sphalerite precipitation is prevented, thereby maintaining a constant Zn inventory throughout both ferruginous and euxinic conditions. These results provide new perspectives and constraints on potential couplings between the trajectory of biological and marine geochemical coevolution.

  • The Cu concentration record for IFs and shales is relatively constant in abundance, reminiscent of the Zn record, raising the possibility of stabilisation of these trace metals by organic ligand complexation.

    “Although the Cu concentration record presented by Chi Fru et al. (2016) for IFs and shales is relatively constant in terms of abundance reminiscent of the Zn record raising the possibility of stabilisation of these trace metals by organic ligand complexation (see Robbins et al., 2013; Scott et al., 2013) - there is a clear trend in the stable isotopes values of Cu.”
  • An alternative model holds that organismal elemental requirements are driven almost entirely by cellular function, with biological requirements decoupled from environmental abundances.

    “The leading alternative to this model is that organismal elemental requirements are driven almost entirely by utility, i.e., cellular function, with shifts in biological requirements decoupled from corresponding environmental abundances (Scott et al., 2013;Robbins et al., 2013;Stüeken et al., 2015a).”

  • Iron formations have proven useful as paleomarine proxies because trace metal content in least metamorphosed units is almost entirely derived from seawater.

    “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).”

  • In the case of Zn, enrichments in black shales and IFs suggest the oceanic Zn reservoir has been relatively constant since the Archean.

    “In the case of Zn, the records of enrichments in both black shales and IFs suggest that the size of the oceanic Zn reservoir has been relatively constant since the Archean (Scott et al., 2013;Robbins et al., 2013).”

  • For elements like Zn, black shales yield independent data on seawater trace element reservoir evolution that supplements the iron formation record.

    “For some trace elements, the black shale record provides valuable independent information about the evolution of seawater trace element reservoirs, such as Zn, complementing the IF record (c.f.Scott et al., 2013 andRobbins et al., 2013).”

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.
