Plate tectonic processes introduce basaltic crust (as eclogite) into the peridotitic mantle. The proportions of these two sources in mantle melts are poorly understood. Silica-rich melts formed from eclogite react with peridotite converting it to olivine-free pyroxenite. Partial melts of this hybrid pyroxenite are higher in Ni and Si, but poorer in Mn, Ca and Mg than melts of peridotite. Olivine phenocrysts compositions record these differences and are used to quantify the contributions of pyroxenite-derived melts in mid-ocean ridge basalts (10-30%), ocean island and continental basalts (many>60%) and komatiites (20-30%). This implies involvement of 2-20% (up to 28%) of recycled crust in mantle melting.
