Advances in Geochemistry and Cosmochemistry, 2(1), 754. https://doi.org/10.33063/agc.v2i1.754 EPMA raw data.xlsx: Electron microprobe raw data for melt, metal and olivine major element composition (and detection limits) of experimental run products Data Tables.xlsx: Six main text tables from Fonseca et al. (2026) that provide: calculated oxygen fugacities, experimental starting compositions, experimental run conditions, summary of the major and trace element contents of each of the experimental run products, calculated modal abundances and mineral/melt partition coefficients Supplementary Tables: Modeled HSE, Mo and W abundances of lunar parental magmas; compilation of literature values for high-field strength and highly siderophile elements in lunar basalts.fO2 calculation from metal-silicate equilibria.xlsx: Spreadsheet that can be used to calculate fO2 of metal-silicate-melt experiments, using the Fe and S contents of metal and FeO contents of coexisting silicate melt based on the activity composition relationships for the Fe-FeS system depicted in Buono, A. S., & Walker, D. (2011). The Fe-rich liquidus in the Fe–FeS system from 1 bar to 10 GPa. Geochimica et Cosmochimica Acta, 75(8), 2072-2087. Also included, is the Monte-Carlo error propagation method used to determine uncertainties on calculated fO2 values. Data Sources: Brunfelt, A. O., & Steinnes, E. (1971).
