The mineralized sequence includes a lower unit of interbedded mafic volcanics, shale and conglomerate overlain by a felsic dome-sill complex. The massive sulphides occur within the felsic rocks, either as exhalative deposits on the top or as replacive masses within the volcaniclastic rocks. The present review has a special aim on structural geology bearing up a genetic model update for the ore. Regional thin-skinned tectonic was clearly identified as the leading Variscan structural style in the district. Several stocked units bounded by thrust-faults display normal polarity on structural and sedimentary criteria basis. Reconstruction of the palaeogeography prior to the tectonic stacking reveals a very extensive mineralizing systemspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Río TintoMassive SulphideIberian Pyrite BeltSouth-Portuguese Zonejournal articleopen access
