Early Earth’s oxygenation

The Great Oxidation Event (GOE) at ~2.4–2.3 Ga and the Neoproterozoic Oxidation Event (NOE) at ~0.8–0.54 Ga, were transformative events that catalyzed the development of global geological, geochemical, and biological processes, paving the way for the diversification of life. Advancements in biogeochemistry, geochemistry, and mineralogy studying the Precambrian record have revealed that these, along with other weaker oxygenation pulses, affected differently the course of Earth's reducing and oxidizing (redox) processes, based on the amount of available oxygen and its effects on Earth’s biogeochemical processes. Understanding the specifics of these events provides valuable insights into the processes that brought Earth’s redox conditions closer to their contemporary state and their impact in shaping life's diversification.
This cross-journal Collection presents articles that enhance our understanding of the two primary oxygenation events that occurred on the Early Earth, as well as the weaker events that preceded and followed them. The articles in this Collection show the connection between the oxygenation events and the changes happening in the solid Earth, its atmosphere, oceans, and all biogeochemical cycles within these systems. We welcome submissions from diverse disciplines, such as biogeochemistry, geochemistry, petrology, and mineralogy.
