嘉宾简介：
Dr. Frederic Moynier is now the professor of Institut De Physique Du Globe De Paris (IPGP) and member of the France University Institute. In 2006, he got his PhD from the ENS Lyon, under the supervise of world-famous geochemist Prof. Francis Albarede, and then conduct his postdoctoral research in Qing-zhu Yin’s group in University of California, Davis. Then he went to Washington University, until 2013, as an assistant and associate Professor. Since 2013, he works in IPGP and was promoted to the full professor in 2016. His research interests mainly focus on the isotope cosmochemistry, including the origin and differentiation of the Earth, the moon and planets, early chronology of the solar system, and the application of stable isotopes to biological and medical sciences. So far, he and his collaborator have published more than 120 peer reviewed papers, and including so many Nature, EPSL, GCA, Chem Geol. and so on, the h-index is about 36, total citation is more than 3,600. Now he is the Editor in chief of EPSL and the Associate editor of GCA. Due to so brilliant contribution to isotope geochemistry, he was awarded the Alfred O. Nier prize in 2012 by Meteoritical Society, the Houtermans medal in 2012 by European Association of Geochemistry, and the Kuno Medal in 2013 by AGU, these awards are granted to the outstanding young geochemist below 35 years old.
报告摘要：
The variation in the abundance of volatile elements is one of the most fundamental difference between planetary bodies. For example the Moon is highly depleted in moderately volatile elements compared to the Earth. To understand the origin of these variations we use the stable isotopic composition of moderately volatile elements as signature of the processes. I will show that the volatile depletion of differentiated bodies such as the Moon or 4-Vesta is controlled by evaporation under relatively low temperature, most probably during the degassing of a magma ocean stage of the planets.
