Resumo - In the NW of the Iberian Masif discordant late-Hercynian granitic plutons are well exposed, of which the Peneda-Gerês massif is one of the most representative. Similarly to other plutons known in the area, it exhibits a dominant subalkaline ferropotassic affinity. Field, petrographic, mineralogical and geochemical data suggest that this massif which is composed of four main granitic units, three of which roughly concentric, results from the subsynchronous emplacement of two distinct granitic magmas. The internal chemical-mineralogical evolutions observed are interpretated as primary trends in which the main petrogenetic process is fractional crystallization.
