The Dynamics of Earth System Oxygenation

Caption: Banded iron formations of the Hamersley Basin, Western Australia, deposited about 2.4 billion years ago. These formations are widely regarded as signifying a key step in the transition to the modern, oxygenated environment. The causes of this transition, especially the connections between the evolving surface environment and the Earth's deep interior, will be investigated by the "Dynamics of Earth System Oxygenation" project.
