About

Jean Alix Barrat is a Professor at the Institut Universitaire Européen de la Mer in France. His research focuses on geochemistry, particularly in areas such as trace element uptake by macroalgae, the origin of primordial helium depletion in mantle plumes, and the implications of extraterrestrial materials on planetary formation. He has authored several recent articles examining the impact of volcanic activity on tektites, chemical weathering in West Africa, and the behavior of rare earth elements in various geological contexts.
