Analyses isotopiques du plomb des minerais et des roches. Les analyses nouvelles sont en italiques. gn : galène ; cp : chalcopyrite ; po : pyrrhotite ; sulf : sulfures polymétalliques à galène ; FK : feldspath potassique ; RT : roche totale. (*) Rapports initiaux corrigés avec t = 201 Ma ; (**) Rapports initiaux (corrigés avec t = 271 Ma). Sauf indication contraire, les ratios n’ont pas été corrigés pour les valeurs de μ faibles et négligeables.

Lead isotope analyses of ore deposits and rocks. New analyses are in italics. gn: galena; cp: chalcopyrite; po: pyrrhotite; sulf: polymetallic sulphides with galena; FK: K-feldspar; RT: whole rock. (*) Initial ratios corrected with t = 201 Ma; (**) initial ratios (corrected with t = 271 Ma). Except otherwise indication, ratios have not been corrected for low and negligible μ values.
