Campo pegmatítico Barroso-Alvão, Distrito de Vila Real, Portugal


Numerous highly evolved aplite-pegmatite bodies, with spodumene or petalite as a dominant Li-mineral, discordantly cut meta-sediments.
Barren pegmatitic veins, pegmatitic veins with beryl, pegmatitic veins with cassiterite and pegmatitic veins with lithium minerals: spodumene, petalite and lepidolite.

A few thousand pegmatite bodies can be found at the Barroso–Alvão pegmatite field. Most of these bodies intrude on metasedimentary rocks, but barren ones can also be found intruding on the two mica granites and the biotite granites. The aplite–pegmatite bodies have different characteristics that enabled defining them into different groups: (i) intragranitic pegmatites (the only group found intruding on granitic rocks); (ii) quartz–andalusite dykes, (iii) barren pegmatites, (iv) spodumene pegmatites, (v) petalite pegmatites, and (vi) lepidolite pegmatites, all intruding on metasedimentary rocks.

Also extends into Braga District.
