<description>El objetivo de este trabajo es dilucidar, petrográfica y geoquímicamente, la naturaleza del proceso o procesos que intervinieron en la generación de la rubefacción presente en la rocas.</description>
<description>Petrographic and geochemical characterization of the rocks underlying the Neoproterozoic-Cambrianangular unconformity in the eastern flank of the Narcea Antiform, provide an insight on the processes involved in the widespread rubefaction present along this contact. The data provide evidence of superposed events related to the sub-aerial weathering during the Precambrian-Cambrian boundary and a further alteration caused, probably, by fluid circulation during the Variscan Orogeny.</description>
