The Neoproterozoic Oxygenation Event - GEO GIRL

This introductory course examines the Neoproterozoic Oxygenation Event, including its timing, geological evidence, possible causes, and effects on Earth’s atmosphere, oceans, and biological evolution. It discusses carbon, sulfur, and strontium isotopes, redox-sensitive trace metals, fossils, weathering, Rodinia’s breakup, and animal ecosystem engineering.
