Evidencias de actividad tectónica cuaternaria en el occidente de la Zona Cantábrica (Puertos de Marabio, Manto de la Sobia)

A reverse fault superposes Carboniferous limestones onto recent cemented scree in the western slope of the Sobia Range (Asturias). The fault is parallel to the bedding and shows slickenlines in both limestone and cemented scree walls. The net slip is up to 6 m. The fault surface is cut by other two sets of transverse faults, which as a whole fit well with a N-S shortening.
