International audience Our knowledge of the sulfur cycle on early Earth is still in its infancy. Nevertheless, there existenough geochemical constraints from the rock record to show that the theoretical mixing modelsproposed by Bao et al. are highly unlikely to account for the range of d34S and D33S valuesrecorded for the microscopic sulfides at the North Pole
