Abstract
The Lusitanian Basin on the western Iberian margin comprises Mesozoic and Cenozoic sediments derived from the surrounding Precambrian to Lower Palaeozoic and Hercynian basement. Apatite fission-track data from Hercynian granitoids to the east of the basin show that the intrusives were being actively eroded throughout the Jurassic and Cretaceous; however, exactly when these rocks first became exposed and eroded is not clear. In this study we have attempted to reconstruct the erosional history of the granitoids of Central Portugal by examining the detrital zircon fission-track signatures contained within post-granite emplacement sediments.
