Abstract

Read online

The GEOCARBSULF model provides the most detailed reconstructions of Phanerozoic O2, but its predictions are not supported by geochemical data. Here, a GEOCARBSULF model rebuilt from first principles, with the addition of an amended sulphur cycle and the latest isotope records, supports a Paleozoic Oxygenation Event.
