SIMS was used to measure the δ34S of pyrite disseminated in burial dolomite matrix of St. George Group at three localities in western Newfoundland. At Main Brook, δ34S values for the pyrite grains show wide variation (-15 to +20 ‰ (n = 20), but are mostly negative. Combined with a paucity of two-pha...
