... magmatic rocks with arc signatures over a short period of time, through the dating of protoliths and deformation-metamorphism of the Évora Massif in Portugal (i.e., gneiss dome). We discuss the hypothesis that the igneous source of the granites of the Évora gneiss dome may represent a Carboniferous...
