The rise of oxygen in Earth’s early ocean and atmosphere
- T. Lyons, C. Reinhard, N. Planavsky
- Geology, Medicine
- Nature
- 20 February 2014
The rapid increase of carbon dioxide concentration in Earth’s modern atmosphere is a matter of major concern. But for the atmosphere of roughly two-and-half billion years ago, interest centres on a… Expand
Iron Formation: The Sedimentary Product of a Complex Interplay among Mantle, Tectonic, Oceanic, and Biospheric Processes
- A. Bekker, Bryan Krapež, +4 authors O. Rouxel
- Geology
- 1 May 2010
Iron formations are economically important sedimentary rocks that are most common in Precambrian sedimentary successions. Although many aspects of their origin remain unresolved, it is widely… Expand
Low Mid-Proterozoic atmospheric oxygen levels and the delayed rise of animals
- N. Planavsky, C. Reinhard, +6 authors T. Lyons
- Environmental Science, Medicine
- Science
- 31 October 2014
Low oxygen limited the rise of animals Oxygen levels in Earth's early atmosphere had an important influence on the evolution of complex life. Planavsky et al. analyzed the isotopic signature of… Expand
Evidence for oxygenic photosynthesis half a billion years before the Great Oxidation Event
- N. Planavsky, D. Asael, +13 authors Olivier J. Rouxel
- Geology, Environmental Science
- 1 April 2014
The early Earth was characterized by the absence of oxygen in the ocean–atmosphere system, in contrast to the well-oxygenated conditions that prevail today. Atmospheric concentrations first rose to… Expand
The ketone metabolite β-hydroxybutyrate blocks NLRP 3 inflammasome – mediated inflammatory disease
- Yun-Hee Youm, K. Nguyen, +14 authors V. Dixit
- 2015

Rare Earth Element and yttrium compositions of Archean and Paleoproterozoic Fe formations revisited: New perspectives on the significance and mechanisms of deposition
- N. Planavsky, A. Bekker, +4 authors T. Lyons
- Geology, Chemistry
- 15 November 2010
The ocean and atmosphere were largely anoxic in the early Precambrian, resulting in an Fe cycle that was dramatically different than today's. Extremely Fe-rich sedimentary deposits i.e., Fe… Expand
Proterozoic ocean redox and biogeochemical stasis
- C. Reinhard, N. Planavsky, +6 authors T. Lyons
- Geology, Medicine
- Proceedings of the National Academy of Sciences
- 20 March 2013
The partial pressure of oxygen in Earth’s atmosphere has increased dramatically through time, and this increase is thought to have occurred in two rapid steps at both ends of the Proterozoic Eon… Expand
Large-scale fluctuations in Precambrian atmospheric and oceanic oxygen levels from the record of U in shales
The atmosphere–ocean system experienced a progressive change from anoxic to more oxidizing conditions through time. This oxidation is traditionally envisaged to have occurred as two stepwise… Expand
Ocean oxygenation in the wake of the Marinoan glaciation
- S. K. Sahoo, N. Planavsky, +6 authors G. Jiang
- Biology, Medicine
- Nature
- 27 September 2012
Metazoans are likely to have their roots in the Cryogenian period, but there is a marked increase in the appearance of novel animal and algae fossils shortly after the termination of the late… Expand
The evolution of the marine phosphate reservoir
- N. Planavsky, O. Rouxel, +4 authors T. Lyons
- Environmental Science, Medicine
- Nature
- 28 October 2010
Phosphorus is a biolimiting nutrient that has an important role in regulating the burial of organic matter and the redox state of the ocean–atmosphere system. The ratio of phosphorus to iron in… Expand
