AB The Iberian Pyrite Belt (IPB) represents one of the largest districts of volcanogenic massivesulfide (VMS) deposits in the world, and is a critical source of base metals (Cu, Pb, and Zn) forEurope. Confirmed resources exceed 1700 Mt of massive sulfides with grades of around 1.2% Cu,1% Pb, and 3% Zn as well as more than 300 Mt of stockwork-type copper mineralization. Significantresources of Sn, precious metals (Au and Ag), and critical metals (Co, Bi, Sb, In, and Se) have also beenevaluated. The genesis of these deposits is related to a complex geological evolution during the lateDevonian and Mississippian periods. The geological record of such evolution is represented by threemain lithological units: Phyllite–Quartzite Group, the volcano–sedimentary Complex (VSC), and theso-called Culm Group. The sulfide deposits are located in the VSC, associated with felsic volcanicrocks or sedimentary rocks such as black shales. The massive sulfide deposits occur as tabular bodiesand replacement masses associated with both volcanic and sedimentary rocks. Their mineralogicalcomposition is relatively simple, dominated by pyrite, chalcopyrite, sphalerite, and galena. Theirorigin is related to three evolutionary stages at increasing temperatures, and a subsequent stageassociated with the Variscan deformation. The present paper summarizes the latest developments in the IPB and revises research areas requiring further investigation.
