1 Supplementary Material for Revisiting the Oxygen Fugacity of Martian Meteorites: Implications for the Redox History of the Mantle of Mars Christopher D.K. Herd, Sophie Benaroya Department of Earth and Atmospheric Sciences, 1-26 Earth Sciences Building, University of Alberta, Edmonton, AB, T6G 2E3, Canada Supplementary Figures Figure S1. Comparison of fO2 results using Fe-based oxybarometry (squares), Eu-based oxybarometry (circles), and V-based oxybarometry (triangles). Individual samples have their own colors and the legends for each geochemical grouping can be found in the plot. All the data plotted are from Tables 1-3. Error bars are ±0.5. 2 Figure S2. Plot of fO2 vs. La/Yb for olivine-phyric shergottites, with V-in-olivine data from Nicklas et al. (2021). Compare with Figure 4. 3 Figure S3. Results of MAGEC degassing models at variable starting fO2 ranging from FMQ to FMQ+1 with ‘high’ volatile abundances from Table 5.
