• Resumen

  • Black shales associated to productive horizon in the Aznalcollar mine have provided miospores assemblages from the Uppermost Devonian (Strunian, LN Miospore Biozone of Western Europe). Stratigraphic location of black shales between felsisc vulcanics and massive sulphides lets to conclude that massive sulphides are Upper Devonian in age. Moreover, the beginning of volcanism in the Iberian Pyrite Belt occured during Devonian times, at least in its easternmost part
