Quantification of atmospheric oxygen levels during the Paleoproterozoic using paleosol compositions and iron oxidation kinetics. Geochimica Cosmochimica Acta. 75 (14): 3982—4004. Bibcode:2011GeCoA..75.3982M. doi:10.1016/j.gca.2011.04.023. The calculations indicate that PO2 increased gradually, linearly on the logarithmic scale, from <∼10−6 to >∼10−3 atm between 2.5 and 2.0 Ga.
