Summary
Earth’s largest reserves of iron ore derive from the giant iron formations, enigmatic rocks that formed in ancient seawater. These extensive iron-rich rocks signal a very different early Earth where life first emerged. However, exactly how these deposits formed is unknown and highly debated, including whether life was involved. This research project will use laboratory experiments to test which pathway(s) generate the most similar chemical fingerprints to the iron formation rocks. Thus, this research will not only help to understand how and where Earth’s largest iron ores formed but will also
