2022 ERC Advanced grants: DEEP SEE project selected

The DEEP-SEE project is one of the projects selected by the European Research Council (ERC). It is led by Alain Manceau, a geochemist emeritus at the Chemistry Laboratory ERC Advanced grants enable scientists to carry out groundbreaking projects that open up new avenues in their disciplinary field. PROJET DEEP-SEE. Fathoming SEquestration and Enrichment of metals in DEEP marine deposits with novel micro-X-ray emission spectroscopy ERC Steinman Rare earth elements (REE) and transition and post-transition metals (TM) are essential to modern life, yet we know little about how they concentrate at Earth's surface, especially on the seafloor, which holds vast reserves. The DEEP-SEE project will shift paradigms on marine metal deposits from chemical composition and resource inventories to a holistic view based on atomic-scale observations and modeling. This research will determine geochemical processes that give rise to some of the highest metal partitionings in supergene ores. First, crystal chemistry of 3+ REE in biogenic vs.
