U-Pb and Ar-39/Ar-40 data constraining the ages of the source, emplacement and recrystallization/cooling events from late- to post-D-3 Variscan granites of the Gouveia area, central Portugal
Late Carboniferous U-Pb ages have been measured on igneous zircon from late- and post-D 3 Sn-bearing two-mica granites from the Gouveia area in the Central Iberian Zone. Inherited zircon from these granites is mainly of Neoproterozoic age, a small amount
