Abstract
► Two studied magmatic epidote granitoids have similar mineral phases and major chemistry but differ in O, Nd and Sr compositions. ► The two magmas followed similar differentiation trends but formed from source rocks that differ in age and composition. ► Magmatic epidote in plutons can crystallize at pressures lower than 5.5 kbar under high fO2 as experimentally foreseen. ► Rapid magma transportation through hot continental crust during peak of metamorphism in early stages of an orogenic cycle prevents epidote dissolution.
