Biography

Yoann Greau is a researcher with a focus on geochemistry and petrology, investigating the composition of the Earth's mantle through the study of mafic and ultramafic rocks. His research centers on the analysis of xenoliths brought to the surface during volcanic eruptions, particularly those from kimberlitic and basaltic magmas. He employs cutting-edge analytical techniques, including laser ablation systems and mass spectrometers, such as MC-ICP-MS, to measure the isotopic distribution of chemical elements. His work also includes geochronology where he mainly uses U-Pb and Lu-Hf isotopes of zircons to determine the ages of rocks and geological events spanning from approximately 4.5 billion to a few million years. Additionally, Yoann is involved in the development of a cloud-based collaborative platform called EarthBank, aimed at preserving, disseminating, and collating geochronological and geochemical isotopic data within a fully relational database environment for geosample registry and data analysis.
