DATA & FILE OVERVIEW
---------------------


1. File List
   A. Filename: Fig1_Al_and_Fe.xlsx         
      Short description: Al2O3 and FeO* wt.% values from martian igneous compositions (Filiberto et al. 2017) as well as synthetic magmas used to calibrate Borisov et al. (2018)'s Eqn. 4. Used to generate Figure 1.        

   B. Filename: Literature_MBvsWCC.xlsx       
      Short description: A compilation of Fe3+/FeT from experiments that have been characterized by Mössbauer spectroscopy and colorimetric wet chemical methods. Used to generate Figure 8.      
        
   C. Filename: regressiondata3.4.csv       
      Short description: Compilation of data (logfO2, temperature, composition, Fe3+/FeT, and uncertainties) from 100-kPa gas mixing furnace experiments on martian magma compositions.

   D. Filename: regression_clean.m       
      Short description: MATLAB code to develop linear regression models for Eqns. 9 and 10, Table 4, and Figure 10. Must have regressiondata3.4.csv in same filepath to operate.
