Collaborative Research: Experimentally testing a new iron silicate model for the origin of Precambrian Iron Formations using iron stable isotope geochemistry

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…
