Carbonate-hosted zinc and lead deposits occur in two settings in the Humber Terrane of western Newfoundland: (i) associated with dolomitized units and breccias in Cambrian and Ordovician shelf-facies carbonate rocks; and (ii) as open-space, vein, and breccia fillings associated with calcite within or near the margins of Carboniferous basins.We report 11 new lead-isotope …

Mixed lead sources in tin metal: Implications for using lead …

Methods for provenancing copper, lead, and silver using the isotopic composition of lead are well-established. Lead isotope analysis holds promise for the study of tin metal as well, as long as one accounts for the U-Th-Pb systematics of cassiterite (SnO 2) and chaîne opératoire of tin production.Although Precambrian cassiterite may contain 10s of ppm Pb or more …

Lead and barium sources in Cambrian siliciclastics and …

Values of the mudstones samples overlap those of galena when corrected for in situ decay of U and Th since galena precipitation (∼450Ma). We thus propose that mudstones constituted a source of lead. Corrected ratios for anomalously Pb-rich mudstones are virtually identical to galena-Pb ratios and may be due to contamination by lead-bearing ...
