The combination of biostra-tigraphic data with the facies architecture of the Neves Corvo massive sulfide deposit allows dating of the two major volcanic events identified in the mine stratigraphy. Both volcanic episodes are represented by submarine and proximal to source vent deposits, with intrabasinal origin and rhyolitic composition. Thick pyroclastic pumice-rich facies of the late Famennian and youngerlavas of the late Strunian (latest Famennian) constitute the host sequence of the massive sulfides. The hydrothermal mineralizing event occurred after the emplacement of the rhyolitic lavas. [ABSTRACT FROM AUTHOR] |
