Isotope (Sr, N d, Pb) data favour the absence of an important input of juvenile magmas in late- to post- tectonic Hercynian felsic magmatism in western Iberia, but suggest a reworking of different crustal protoliths, including oceanic metabasic rocks accreted to mid-to-Iower crustal levels during the early stages of the collision. I-type granites were derived from different meta-igneous protoliths ranging from metabasic to felsic compositions depending on their geographical position from the external (e.g. Galicia-N Portugal, GNP) to the innermost continental areas (Spanish Central System and Los Pedroches Batholiths). The GNP 1- type pIu tons related to eo-Hercynian accretional terranes have lower initial 87Sr/86Sr ratios, lower negative εNd values, and higher 206PbP04Pb ratios than other I-type granites of the Central Iberian zone. These more isotopically primitive Hercynian I-type granites are important in tracking pre-Hercynian accreted oceanic lithosphere terranes.engjournal articlehttp://www.springer.com/journal/710open access552.3(234.1)Post-tectonics plutonicsGranitesCentral IberianSpainPetrología
