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

Inherited zircon from these granites is mainly of Neoproterozoic age, a small amountKeywords: argon-argon dating; Cambrian; cooling; Devonian-Carboniferous boundary; emplacement; Gondwana; granite; Hercynian orogeny; muscovite; Ordovician-Silurian boundary; Proterozoic; recrystallization; uranium-lead dating; Central Iberian Zone; Portugal Emplacement ages; Inheritance; Muscovite; Recrystallization/cooling ages; ZirconU-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 Portugal201210.1016/j.lithos.2012.02.0122016-02-24
