Geochemical analyses of magma reveal a dynamic activity of the terrestrial lithosphere 4 billion years ago - Université Grenoble Alpes

Thanks to a geochemical analysis platform unique to the world at the Institute of Earth Sciences in Grenoble (UGA/CNRS/USMB/IRD/Université Gustave Eiffel), scientists from Grenoble Alpes University have highlighted, contrary to current theories, a dynamic activity of tectonics of the plates of our planet 4 billion years ago. This discovery centered on geochemical analyses of magmatic inclusion and supplemented by numerical modelling carried out …
