* = overgrowth, † = average of different veins and clusters, ‡ = blebs in orthopyroxene. QUILF calculated according to Andersen et al. (1993) based on the two-pyroxene equilibrium. Putirka calculated according to Putirka (2008) based on the two-pyroxene equilibrium. Ti-in-amphibole temperature calculated according to Ernst and Liu (1998).
