Source data for “Coupled slab-derived Fe3+-rich melt input and refractory harzburgite melting generate ultra-oxidized arc basalt”

Abstract

Source data supporting the manuscript “Coupled slab-derived Fe3+-rich melt input and refractory harzburgite melting generate ultra-oxidized arc basalt” by Hagiwara et al. The repository contains (1) Supplementary Data.xlsx, comprising Supplementary Tables 1–20; (2) Source_Data_Main_Figures.xlsx, containing numerical source data for main-figure elements not already provided directly in the Supplementary Data; and (3) README.txt. Source_Data_Main_Figures.xlsx includes rhyolite-MELTS fractional-crystallization trajectories (Fig. 3a), Fo–Ni fractional-crystallization trajectories (Fig. 3b), near-fractional melting calculations (Fig. 3f), D80new slab P–T paths (Fig. 6), H-diffusion model coordinates and literature S-isotope comparison data (Fig. 8), and comparative global arc data used in Fig. 9. FOB analytical data used in Fig. 9 are reported in Supplementary Table 1 and are not duplicated in the source-data workbook. Published comparison data retain provenance to the original publications.
