Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Per-mo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ^34 S values of the ores commonly fall within the accepted mantle range of 0±2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ^34 S value is also within this range.
