Secondary ion mass spectrometry (SIMS) was used to measure the δ 34 S of pyrite disseminated in burial dolomite matrix of Boat Harbour formation at Main Brook and Daniel’s Harbour (about 130 km apart). At Main Brook, δ 34 S values for the pyrite grains show wide variation (–15 to +20‰ (n = 20)), but...
