Multiple sulfur isotopes in Paleoarchean barites identify an important role for microbial sulfate reduction in the early marine environment

Bedded barites from the Barberton greenstone belt (South Africa and Swaziland) preserve a comprehensive record of atmospheric, oceanic and microbial processes involved in the formation and evolution of the Paleoarchean (3.6–3.2Ga) oceanic sulfate reservoir. Here, we report multiple sulfur isotopic c...
