Results show that the main magmatic event was placed between 387-392 Ma, indicating the oldest volcanism in the Iberian Pyrite Belt so far. Inherited and detrital zircon ages suggest affinity to Laurussian and Avalonia (s.l.) peri-Gondwanan sources, which provides additional constraints on the paleogeographic positioning of the Iberian Pyrite Belt during the Variscan Cycle.porIberian Pyrite BeltSalgadinho depositU–Pb geochronologyFaixa Piritosa IbéricaJazida do SalgadinhoGeocronologia U-Pbconference object
