  • The oxidative deposition of iron in the Banded iron-Formations can be quantitatively accounted for by direct abiotic photo-oxidation, by extrapolating from laboratory conditions and making reasonable assumptions about the early Earth and its oceans. Within this model, iron supply was the limiting factor, the Precambrian ocean surfaces were iron-depleted, and hydrogen would have been released into the atmosphere at a rate controlled by Fe(II) mixing. Other mechanisms operating in parallel are… CONTINUE READING
