M. A1 Sáez Ramos, Reinaldo AB Black Shale Level of Las Herrerías Sindine is Tournaisian-Upper Visean (close to basal Namurian) in age and, it is stratigraphically equivalent to the Vulcano Sedimentary Complex in other places of the Iberian Pyrite Belt. Mapping features, including lateral pinch out of the volcanic levels, and palynological data point to a condensed sequence s.s. for this black shale level PB Sociedad Geológica de España YR 2000 FD 2000 LK http://hdl.handle.net/10272/9794 UL http://hdl.handle.net/10272/9794 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 15 jun 2026
