Allanite composition and texture. a Resorbed and zoned allanite from the Miagliano tonalite (BSE image). b Data of allanite in XFerri-epidote versus XClzoi diagram [XClzoi = Al/(Al + Mg + Fe2++Fe3+); XFerri-epidote = Fe3+/(Al + Mg + Fe2++Fe3+)]. c Ca versus Mg content in allanite and epidote. Note the high Mg content in the epidote
