Extended Data Table 1 Tukey–HSD pairwise comparison test of average mean ophiolite Fe3+/ΣFe ratios for the given age bins

From: A record of deep-ocean dissolved O2 from the oxidation state of iron in submarine basalts

  1. Data used are the mean Fe3+/ΣFe ratios for a given ophiolite. Values are P values. Green indicates a P value < 0.05 and red a P value > 0.05.
