Géochimie et analyse élémentaire

This cluster of papers focuses on the geochemistry, formation mechanisms, environmental impacts, and biological interactions of manganese oxides in sedimentary environments. It explores the relationships between manganese oxides, rare earth elements, trace element composition of sedimentary rocks, provenance analysis, and weathering processes. The cluster also investigates the potential of deep-ocean mineral deposits as a source of critical metals for high- and green-technology applications.
