Abstract We present a structural update to the thermodynamic model for calculating peridotite phase relations and melt compositions at 0·01 60 kbar from 600 °C liquidus in system K2O–Na2O–CaO–FeO–MgO–Al2O3–SiO2–TiO2–Fe2O3–Cr2O3 (KNCFMASTOCr), based on of Holland et al., 2018 [Melting Peridotites through Granites: A Simple Thermodynamic Model System KNCFMASHTOCr. Journal Petrology 59, 881–900]. ...
