What do the ancient oceans tell us about the early evolution of our planet?
The oceans act as an interface between the Earth’s atmosphere, the continents and the deep mantle via surface processes, erosion, and hydrothermalism. The aim of the EU-funded GOforISOBIF project is to investigate the composition of early seawater recorded in Precambrian banded iron formations to provide unique insight into the processes that have affected the Earth’s major reservoirs at the beginning of our planet history. Using new and innovative geochemical tools, the project will focus on 3 first-order questions: 1) the origin, composition and size of the first continents; 2) the detection of whiffs of oxygen in the early oceans before the great oxidation event (GOE); 3) the relationship between hydrothermal activity and global mantle geodynamics.
