Isua Greenstone Belt, sulfur isotope data (NERC Grant NE/V010824/1)
Triple-sulfur isotope data from schists and carbonates in the Eoarchean Isua Greenstone Belt (3.7 Ga), using a new leaching technique and a multi-collector ICP-MS. The results reveal distinct pattern between the two lithologies and demonstrate an atmospheric contribution of sulfur in both cases. This may support the notion that these rocks represent metamorphosed marine sediments. However, hydrothermal alteration needs to be assessed in more detail to verify the antiquity of these signatures.

Sulfur was leached from rock powders with aqua regia; the solutions were dried and redissolved in dilute nitric acid and then purified for sulfate with a Prepfast. The purified solutions enriched in sulfate were analysed by inductively-coupled plasma mass spectrometry at the University of St Andrews
