abstract = {U-Pb dating of zircons from ryolites intercalated within the Narcea Antiform Neoproterozoic rocks was performed by laser ablation ICP-MS). The age of the ryolite is 559±3 Ma which allows the separation of two different units within the previously established Tineo Series. It is suggested that a terrane-transfer related pull-apart environment could have been the ideal setting for the genesis of these rocks in accordance with previously proposed models for the Neoproterozoic evolution of this region},
abstract = {Se han datado mediante U-Pb circones de riolitas intercaladas en las rocas Neoproterozoicas del Antiforme del Narcea, por medio de ablación láser. La edad obtenida es de 559 ±3 Ma, la cual que permite la separación de dos unidades estratigráficas distintas dentro de las previamente conocidas como Serie de Tineo. Se sugiere que su origen pudiera estar relacionado con cuencas transtensivas relacionadas con la migración de terrenos a lo largo de la evolución Neoproterozoica del margen septentrional de Condwana},
