dc.description.abstractDetrital zircons from greywackes belonging to an Ordovician volcanosedimentary-igneous complex in NW Spain were dated using the laser ablation-inductively coupled plasma-mass spectrometry technique. U-Pb results indicate the existence of three Precambrian crustal sources in NW Iberia. The age grouping datetd at c. 590-620 Ma. confirms the presence of a Cadomian-Avalonian basement in this zone. The second age group (c. 1.1-1.2 Ga) is the first evidence for a Grenvillean age crustal component in NW Iberia. The age grouping dated at c. 1.9-2.0 Ga corresponds to the age of the Icartian igneous basement exposed in other areas of the European Variscides.es_ES
