The Fregeneda–Almendra pegmatitic field is a geologic area in the Iberian Peninsula extending across the Portuguese district of Guarda and the Spanish province of Salamanca. Part of the Central Iberian Zone,[1] it is located in the western part of a narrow E–W metamorphic belt.[2] It consists of a variety of granitic pegmatites, where some rocks are rich in lithium. The Li minerals include spodumene, petalite, lithian muscovite and montebrasite.[3]

A mining site for the extraction of lithium, tin, niobium and tantalium is located in La Fregeneda area.[4]
