  • A. Lomagundi event chosen
    The Lomagundi event was a prolonged Paleoproterozoic episode of unusually high carbon isotope ratios in marine carbonates, interpreted as evidence for a major global increase in oxygen production and organic carbon burial.
  • B. Cadomian orogeny

  • D. Sturtian glaciation
    The Sturtian glaciation was a major global ice age during the Neoproterozoic, when extensive ice sheets may have covered much of Earth’s surface in one of the most severe glacial events in the planet’s history.
  • E. Baikal orogeny
    Baikal orogeny is an ancient mountain-building event that shaped parts of Siberia and Central Asia during the late Precambrian to early Paleozoic eras.
