Las pizarras negras del

Abstract

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
