Probing the Geochemistry of the First Oceans with Novel ISOtope Proxies in Banded Iron Formations (BIFs): New Perspectives into Early Continental Weathering, Ocean Oxygenation and Mantle Geodynamics

Since the beginning of Earth’s history, the oceans acted as an interface between the atmosphere, the continents, and the mantle via atmospheric exchange, weathering, sedimentation, and submarine volcanism. Such interactions make the composition of early seawater a unique recorder of the processes that have affected the Earth’s major reservoirs. Yet, this record has not been explored in details. Here, I propose to investigate the geochemistry of the first oceans that is recorded in Precambrian banded iron formations (BIFs) to address first-order questions related to the early evolution of our planet. The proposed project combines well-established radiogenic isotopic systems (Lu-Hf,…
