Metasomatism at a granitic pegmatite-dunite contact in Galicia; the Franqueira occurrence of chrysoberyl (alexandrite), emerald, and phenakite; discussion and reply
The Canadian Mineralogist (December 1996) 34, Part 6: 1329-1336

Abstract

In a recent description of this beryl occurrence it was interpreted according to the classical theory of exometasomatism. It is here argued that the occurrence of phenakite, alexandrite and emerald at Franqueira is another example of multistage Be mineralization related to regional metamorphism.
