AB The Iberian Pyrite Belt (IPB) is recognized as having one of the major concentrations ofvolcanogenic massive sulfide (VMS) deposits on Earth. Original resources of about 2000 Mt of massivesulfides have been reported in the province. Recent classifications have considered the IPB deposits asthe bimodal siliciclastic subtype, although major di erences can be recognized among them. The mainones concern the hosting rocks. To the north, volcanic and volcaniclastic depositional environmentspredominate, whereas to the south, black shale-hosted VMS prevail. The mineral composition isquite simple, with pyrite as the main mineral phase, and sphalerite, galena, and chalcopyrite as majorcomponents. A suite of minor minerals is also present, including arsenopyrite, tetrahedrite–tennantite,cobaltite, Sb–As–Bi sulfosalts, gold, and electrum. Common oxidized phases include magnetite,hematite, cassiterite, and barite. The spatial relationship between all these minerals provides a veryrich textural framework. A careful textural analysis reported here leads to a general model for thegenetic evolution of the IPB massive sulfides, including four main stages: (1) Sedimentary/diageneticreplacement process on hosting rocks; (2) sulfides recrystallization at rising temperature; (3) metaldistillation and sulfides maturation related to late Sb-bearing hydrothermal fluids; and (4) metalremobilization associated with the Variscan tectonism. The proposed model can provide new toolsfor mineral exploration as well as for mining and metallurgy.
