U–Pb Geochronology of Iberian Granitoids by alexandraribeirodamota is a document available to read on EtoBox.
This study investigates U–Pb zircon and monazite geochronology of post-collisional Hercynian granitoids in the Central Iberian Zone of Northern Portugal. Twelve granitic units were analyzed, revealing a chronology of granitoid emplacement spanning approximately 30 million years, from 319 to 280 Ma, with distinct phases related to the last ductile deformation (D3) and subsequent fragile deformation (D4). The findings indicate significant geological transitions in tectonic regimes and magmatic activity during
