RT Journal Article T1 Paleometeorización vs. Paleoalteración en la superficie de discordancia Proterozoico-Cámbrico en el Antiforme del Narcea T1 Paleoweathering vs. Paleoalteration at the Proterozoic-Cambrian uncomformity surface ¡n the Narcea Antiform A1 Gutiérrez Alonso, Gabriel A1 Blanco Sánchez, J. A. A1 Macfarlane, A. A1 Fernández Suárez, Javier AB Petrographic and geochemical characterization of the rocks underlying the Neoproterozoic-Cambrian angular unconformity in the eastern flank of the Narcea Antiform, provide an insight on the processes involved in the widespread ruhefaction 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 PB Sociedad Geológica de España YR 2004 FD 2004 LK http://hdl.handle.net/10272/8951 UL http://hdl.handle.net/10272/8951 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
