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.
