Jean-Alix BARRAT

Jean-Alix BARRAT is a University Professor at the University of Western Brittany and a researcher at the LEMAR Laboratory. His work focuses on geochemistry, planetary science, and environmental pollution, particularly through the study of rare earth elements, meteorites, and isotopic compositions.

• University of Western Brittany
• LEMAR Laboratory

His research interests include:

• Trace element analysis in environmental systems
• Geochemical studies of Martian and other planetary meteorites
• Isotopic variations in primitive planetary bodies
• Environmental contamination by rare earth elements
• Impact processes and tektite formation
• Mantle plume geochemistry

Recent publications highlight his contributions to understanding:

• Rare earth element dynamics in beers and biological systems
• New meteorite discoveries (CI1, aubrites, H-chondrites)
• Isotopic constraints on solar system evolution
• Trace element redistribution in marine and terrestrial environments
• Volatiles and noble gas signatures in planetary bodies
