| Abstract |
Sedimentological, textural, and microscale analyses of the Mount McRae Shale revealed a complex postdepositional history, previously unrecognized in bulk geochemical studies. We found that metal enrichments in the shale do not reside with depositional organic carbon, as previously proposed by Anbar et al., but with late-stage pyrite, compromising claims for a “whiff” of oxygen ~50 million years before the Great Oxygenation Event. |
