The Late-Variscan Tres Arroyos granite-pegmatite system is situated in the southern Central Iberian Zone of the Variscan Iberian Massif, to the southwest of the easternmost segment of the Nisa-Alburquerque (NA) batholith. The system intruded into a Precambrian low-grade metasedimentary sequence, belonging to the metamorphic Schist-Greywacke Complex (SGC). The main facies of the NA batholith comprise a peraluminous, porphyritic monzogranite and a minor two-mica leucogranitic facies (González-Menéndez 1998). Quartz, feldspar, biotite and muscovite are the main minerals, with Al silicates as minor phases. In the Tres Arroyos area the batholith exhibits a marginal facies (Gallego-Garrido 1992) characterized...
