Resum

Several late leucogranite small plutons appear in the high grade zone of the continental domain (CD), in the Aracena metamorphic belt (AMB). These leucogranites cross-cut the structures due to the main tectono-metamorphic events. The main ferromagnesian minerals in these granites are clinopiroxene and amphibole, the geochemical patterns are characteristics of metaluminous granites. Multielement and tectono-magmatic discrimination diagrams suggest that these metaluminous granites were intruded in the last stages or after a continental collision event
