Figure 5
Trajectories of points in Emax − E50 plots for simulated mixtures of: a–A: basalt glass–6-line ferrihydrite; b–B: fayalite (Fe2+SiO4)–hematite (Fe3+2O3); c–C: hercynite (Fe2+Al2O4)–goethite (FeOOH). Data are tabulated at fractions of the Fe3+ component (capital letters) of 0, 0.25, 0.5, 0.75 and 1. |
