Bernard Bourdon (LGL), ERC Advanced Grant

Understanding the mechanisms that created the planets of our solar system is one of the challenges faced by the scientific community. With his project, geophysicist Bernard Bourdon is on an unprecedented mission to further our knowledge. A CNRS research director at the Lyon geology laboratory (LGL), he is one of the 277 European laureates of a 2015 Advanced grant awarded by the European Research Council (ERC). "When I was young, I loved volcanoes," Bourdon modestly says from his office at the ENS de Lyon's geology lab. The scientist, who has already been able to travel to Java, chose to explore the topic as part of his thesis: at what speed does magma come out? How does it evolve? How much time does it take for lava to crystallize? Bourdon works with mass spectrometry, a very useful tool in geochemistry. The idea is to measure the presence of isotopes in rocks to understand how they formed. Some of them disintegrate and the state of their degradation can help date the samples.
