a Phase diagrams for nitrogen-bearing and nitrogen-free slab sediments at 6–12 GPa. b Chemical compositions of phengite vs. pressures and (c) K-hollandite vs. temperatures. Error bars represent the standard deviation based on Monte Carlo simulations that compound uncertainties for oxides (wt%). The source data for the NH3-bearing (orange) and NH4NO3-bearing (magenta) systems are provided in Supplementary Data 1. The data for the pelite-H2O system (cyan) are from refs. 39,79,80,81 and the data for the pelite-H2O-CO2 system (green) are from refs. 81,82,83,84.
