Fig. 2: Cross plots of geochemical data.
From: Anomalous fractionation of mercury isotopes in the Late Archean atmosphere
Uncertainties on Hg isotope data correspond to the larger value of either the measurement uncertainty of replicate digests of MESS-2 or the uncertainty of repeated measurements of UM-Almadén; analytical uncertainties for additional data are encompassed within each individual data point. These plots demonstrate a lack of correlation between Hg (ppb) and total sulfur content (S wt%) (a), and generally positive correlations between Hg (ppb) and total organic carbon (TOC, wt%) (b), Δ199Hg and Δ201Hg (both in ‰) (c), and Δ199Hg and Δ200Hg (both in ‰) (d).
