minerai sulfuré

CONT: Le gisement de Bisbee (Arizona), constitué par d'énormes lentilles de minerais sulfurés (4 à 9 % Cu) interstratifiés dans des calcaires autour d'une intrusion de porphyre cuprifère, est [...] exploité en découvert.
CONT: Les pyrites [...] sont les seuls minerais métalliques sulfurés exploités intentionnellement pour la production du soufre.

CONT: The normal occurrence of sulfide ores is ... as discordant, nonstratified masses occupying fissure veins ... or other spaces produced during the postconsolidation tectonic deformation of the wall rocks ... Such deposits are unquestionably epigenetic, that is to say, of different origin from the enclosing rocks.
CONT: Large quantities of sulfur and nitrogen oxides are emitted into the atmosphere by the combustion of fossil fuels and the smelting of sulfide ores, particularly in the heavily industrialized and urbanized North Temperate Zone.
