In primitive hydrous arc-magmas and under pressure conditions typical of the lower crust calcic amphibole precedes the crystallisation of plagioclase and follows that of olivine, spinel and pyroxene (e.g., Muentener & Ulmer, 2006). Among the early minerals, amphibole is the sole capable to incor...
