Abstract (EN): The Barroso-Alvao region (BA) and Almendra-Barca d'Alva region (AB) have high mineral resources potential for LCT (Li, Cs, Ta) pegmatites. Both pegmatite fields are located in the NW part of the Iberian Pegmatitic Belt. Pegmatite veins are hosted in low- to medium-grade metamorphic rocks and are surrounded by highly evolved synorogenic two-mica granitoids. The lithium mineralization occurs within pegmatite-aplite veins mainly in the form of lepidolite, spodumene, petalite and accessory montebrasite-amblygonite, cookeite and eucryptite. Based on successful geochemical exploration results obtained in the BA region, similar methodologies are now being applied to the AB region with successful identification of lepidolite, petalite and spodumene bearing pegmatite-aplite veins.
