Abundance of Banded Iron Formation s (BIFs) peaked early this period. BIFs were formed as anaerobic Algae produced waste Oxygen that combined with Iron , forming Magnetite (Fe3O4, an Iron Oxide ). This process cleared iron from the oceans, presumably turning greenish seas clear. Eventually, without an oxygen sink in the oceans, the process created the oxygen-rich Atmosphere of today. The Huronian Glaciation began in the Siderian 2400 Ma and ended in the late Rhyacian 2100 Ma. SEE ALSO REFERENCES |
