Mass-dependently fractionated (MDF) sulfur isotopes in sedimentary sulfides and sulfates can provide information on the past activity of microbial metabolisms and serve as a proxy for the concentration of seawater sulfate. In conjunction with these proxies, mass-independently fractionated (MIF) sulfur isotopes can be used to track the rise of atmospheric oxygen. The anoxic–oxic transition of the surface environment in the Paleoproterozoic has been constrained by MIF sulfur in 2.47 Ga sulfides… CONTINUE READING
