• The onset and early evolution of life (2006, background): “In this proximal zone elemental sulfur polymers, generated in the atmosphere by photolysis of H 2 S and SO 2 (Pavlov and Kasting, 2002) and sedimented within the mounds, could stand in as an electron acceptor in place of ferric iron, albeit at a lower potential (Fig.”
