AB VMS deposits in the Iberian Pyrite Belt (IPB), Spain and Portugal, constitute the largestaccumulation of these deposits on Earth. Although several factors account for their genetic interpretation, a link between volcanism and mineralization is generally accepted. In many VMS districts,research is focused on the geochemical discrimination between barren and fertile volcanic rocks,these latter being a proxy of VMS mineralization. Additionally, the volcanological study of igneoussuccessions sheds light on the environment at which volcanic rocks were emplaced, showing anemplacement depth consistent with that required for VMS formation. We describe a case on theEl Almendro–Villanueva de los Castillejos (EAVC) succession, Spanish IPB, where abundant felsicvolcanic rocks occur. According to the available evidence, their geochemical features, εNd signatureand U–Pb dates suggest a possible link to VMS deposits. However, (paleo)volcanological evidencehere indicates pyroclastic emplacement in a shallow water environment. We infer that such a shallowenvironment precluded VMS generation, a conclusion that is consistent with the absence of massivedeposits all along this area. We also show that this interpretation lends additional support to previous models of the whole IPB, suggesting that compartmentalization of the belt had a major role indetermining the sites of VMS deposition
