abstract = {VMS deposits in the Iberian Pyrite Belt (IPB), Spain and Portugal, constitute the largest
accumulation 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 igneous
successions sheds light on the environment at which volcanic rocks were emplaced, showing an
emplacement depth consistent with that required for VMS formation. We describe a case on the
El Almendro–Villanueva de los Castillejos (EAVC) succession, Spanish IPB, where abundant felsic
volcanic rocks occur. According to the available evidence, their geochemical features, εNd signature
and U–Pb dates suggest a possible link to VMS deposits. However, (paleo)volcanological evidence
here indicates pyroclastic emplacement in a shallow water environment. We infer that such a shallow
environment precluded VMS generation, a conclusion that is consistent with the absence of massive
deposits 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 in
determining the sites of VMS deposition},
