Significance of detrital zircons in Siluro-Devonian rocks from Iberia

Seven samples of Siluro-Devonian sedimentary rocks from the Cantabrian and Central Iberian zones of the Iberian Variscan belt have been investigated for provenance and contain four main age populations in variable relative proportion: …

Iberian late-Variscan granitoids: Some considerations on crustal sources and the significance of mantle extraction ages

A suite of post-tectonic granitoids (mostly peraluminous, broadly I-type granodiorites and monzogranites) and mafic rocks from NW Iberia with crystallization ages between ca. 309 and 290 Ma has been investigated for Sm–Nd isotopes and inherited …
