Figure 3.
(A) δ202Hg vs Δ199Hg, and (B) Δ201Hg vs Δ199Hg in PBM (n = 52).
The shaded field is the range for Indian coal after Sun et al. (2014). 2SD determined by reproducibility of the UM-Almaden standard and repeat analysis of samples triplicates. The arrow shows -0.5 ‰ shift in δ202Hg of PBM relative to feed coal as modelled by Sun et al. (2014).
