Abstract
España es el principal exportador mundial de pizarras, debido tanto a la calidad excepcional de sus yacimientos, como a los avances tecnológicos que se han ido incorporando en los últimos años en el proceso productivo. El presente artículo describe de manera general los principales litotectos de la Península Ibérica, incluidos dentro del área noroeste del Macizo Ibérico Hespérico, y entre los que destacan los pertenecientes a la Formación Pizarras de Luarca, que en Portugal se correlaciona con la Formación Pizarras de Valongo. En total, en la Península Ibérica se pueden distinguir 12 distritos mineros de pizarra para cubiertas, los cuales son valorados como yacimientos según criterios de tipo minero y petrológico.
The exceptional quality of the slate of northwest Spain and the new technological advances incorporated in the last years into the production process have made the country the largest roofing slate producer in the World. This article describes the main slate lithotecs of the Iberian Peninsula. Most of them belong to the Luarca Slates Formation, which in Portugal correlates into the Valongo Slates Formation. Following mining and petrological criteria, a total of 12 mining districts of the Iberian Peninsula have been evaluated as roofing slates deposits.
