Extended Data Figure 2: Summary of mixing model results for each south Greenland terrane.
From: South Greenland ice-sheet collapse during Marine Isotope Stage 11
MD99-2227 inferred silt provenance expressed as median flux of CaCO3-free silt (a) and median percentage of total CaCO3-free silt (b). Values for the Holocene and LIG are recast from CaCO3-free silt Sr–Nd–Pb isotope ratios in ref. 16. Thick black and thin grey vertical lines mark the 16.5–83.5% and 2.5–97.5% quantile ranges, respectively, of valid mixing solutions from all 10,000 model runs. Uncertainty estimates are conservative, because the Monte Carlo procedure for random endmember determination can result in unrealistic combinations of source-terrane isotope composition and elemental concentration. Note different y-axis scale for Palaeogene volcanic data.
