Corrigendum


Correction to: Geochemical Perspectives Letters v3, n2, 210-220, doi: 10.7185/geochemlet.1724, published on 15 June 2017.

The authors have identified an error in Figures S-8 and S-9 of the Supplementary Information accompanying the original article. Figures S-8 and S-9 have now been corrected in the online and PDF versions of the Supplementary Information and the correct figures are shown below.


Figure S-8 Modelled seawater composition (δ238U, δ98Mo) for the early Cambrian steady states before and after the Cambrian Stage 2–3 event. The left most point represents 100 % burial in anoxic settings (fU = fMo = 1). At each step point towards the right, fU decreases 10 % (i.e. 90 %, 80 %, 70 %, etc.). The estimated composition of the δ238U and δ98Mo of early Cambrian seawater in ‰ before and after the event are (-0.65, -0.70) and (1.4, 1.1), respectively, Error bars show ±0.03 ‰ and ±0.15 for δ238U and δ98Mo, respectively.


Figure S-9 The predicted composition of seawater at steady state for a = 1.15–1.38 is consistent with observations at the peak of the oxygenation event (δ238U = –0.45 ‰, δ98Mo = 2.0 ‰) with only 30 ± 10 % U removal into anoxic settings (corresponding to 25 ± 10 % and 19 ± 8 % Mo removal for a = 1.15 and 1.38, respectively).
