N2 - Garnets from metamorphosed ironstones from near Collobrieres, southern France, are some of the most almandine-rich garnets yet reported. They occur in a quartz-free assemblage, containing fayalite, grunerite, magnetite, and apatite. Peak metamorphic conditions are estimated to be 630 ± 60°C and 5 ± 2 kbar. The occurrence of fayalite indicates relatively reduced metamorphic conditions, below FMQ. The presence of Fe3+ in the garnets under such conditions suggests similar or larger amounts of Fe3+ should be present in aluminous garnets in medium and high grade metamorphic rocks. -from Authors
