Abstract (EN): A fluid inclusion study on quartz and cassiterite from the Neves Corvo Cu and Sn ores and also from the metavolcanic and metasedimentary lithologies above the ores was performed in order to characterize the fluids participating in the ore genesis. Except for the massive sulphide ores, all the samples have shown evidences of being affected by metamorphism. The strongest evidence is the ubiquitous aqueous carbonic inclusions that have high fluid pressures, attaining 300 MPa at the homogenization temperature. This precludes their formation on or near the seafloor. It is suggested that, at least in part, the Neves Corvo richness is a consequence of intense remobilization acting during the orogenic metamorphism.
