Transformación de andalucita a sillimanita en granitos peralumínicos del batolito de los Montes de Toledo: implicaciones petrogenéticas

The Montes de Toledo Batholith comprises several felsic peraluminous granitic plutons characterized by the presence of two Al2SiO5 polymorphous: andalusite and sillimanite (as fibrolitic variety). Textural features indicate an igneous origin for andalusite, variably replaced by muscovite and fibroli...
