Extended Data Fig. 2: Estimated incoming fluid oxygen isotope composition from synthetic datasets.
From: Limited Archaean continental emergence reflected in an early Archaean 18O-enriched ocean
Results of ‘leave-one-out’ inversions, removing one sample each time (21; 18; 23). Each set of inversions has the same number of runs as there are samples for each set. Arrows indicate imposed incoming fluid δ18O, and inset shows the models on the same isotopic scale as the crustal sections in Fig. 2.
