When scientists discuss the great oxygenation event, they are referring to a time when the transition from the mildly reducing Archean atmosphere-ocean system to the oxygenated atmosphere and shallow oceans of the early Paleoproterozoic that started between ~2.4 and 2.3 Ga and ended between 2.1 and 2.0 Ga.

  • here The Great Oxidation Event, also called the Great Oxygenation Event, the Oxygen Catastrophe, the Oxygen Revolution, and the Oxygen Crisis, was a time interval when the Earth's atmosphere and the shallow ocean first experienced a rise in the amount of oxygen.
  • in this event Gradually, the accumulated oxygen started escaping into the atmosphere, where it reacted with methane. As more oxygen escaped, methane was eventually displaced, and oxygen became a major component of the atmosphere.
  • The Great Oxygenation Event (GOE) was the creation of free oxygen in our atmosphere. It was caused  by cyanobacteria doing photosynthesis
