The objective of the proposed work is to move forward our understanding of the evolutionary adaptations of early life to the increasing atmospheric oxygen concentration. Our aim is to characterize the evolving biosphere and the changing environments across the 2.45 to 2.32 Ga old Great Oxidation Event and the ~0.8 to 0.54 Ga old Neoproterozoic Oxidation Event. To achieve this goal, we wil…
Banded Iron Formations (BIFs) are chemical archives of Precambrian seawater chemistry and post-depositional iron cycling. Given that BIF accumulated on the seafloor for over two billion years of Earth's early history and that their deposition is coeval with the progressive oxygenation of the atmosphere and hydrosphere, changes in their chemical, mineralogical, magnetic properties and isot…
The atmosphere and oceans became oxidized across two main transitional periods, the Great Oxidation Event (~2.45 and 2.2 Ga) and the Neoproterozoic Oxidation Event (~0.80 and 0.54 Ga). Pieces of evidence are found in South Africa, North America, Western Australia and Russia, but the real timing, duration, mechanism and range of O2 increase are still unsolved question due to poor age const…
The aim of Camille Yann Rossignol postdoctorate is to establish the chronostratigraphy at high resolution of the Minas Supergroup, Minas Gerais region. The study includes characterizing the sedimentological environment based on outcrop exposures and the drill core library stored at Vale (Belo Horizonte) combining bulk and in situ trace element analysis, Hf, Nd and O isotopic tracers and U…

The early Paleoproterozoic (2.5 - 2.1 Ga) was a period of major environmental and climatic changes, marked by the rise of atmospheric oxygen and the onset of multiple glaciations, the oldest one at ca. 2.45 Ga of possible global extension (Snowball Earth event). This is at odd with the sedimentary successions of similar age in the Minas Basin, São Francisco Craton, for which no evidence o…
The Great Oxidation Event (GOE, ~ 2.5 - 2.2 Ga) and the Neoproterozoic Oxidation Event (NOE, ~ 0.85 - 0.54 Ga) record the time when the Earth's became O2-rich. These two periods were coeval with the emplacement of sub-aerial Large Igneous Provinces (LIPs) and at least 3 glacial events, some of which of global extent (Snowball Earth). Despite the geological evidence through at least five c…
