abstract = {Black shales associated to productive horizon In the Aznalcollar mine have provided mlospore assemblages from the Uppermost Devonian (Strunian, LN Miospore Blozone of Western Europe).
StratEgraphic location of black shales between felsic volcanics and massive sulphides lets to conclude that massive sulphides are Upper Devonian In age. Moreover, the beginning of volcanism in the Iberian Pyrite Belt occurred during Devonian times, at least in its easternmost part},
