Stable isotope fractionation of S, Te, and Pd and the roles of core formation and late accretion on siderophile volatile elements in the Earth (B02+)

• Subject Area: Mineralogy, Petrology and Geochemistry
• Term: from 2016 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 263649064

The aim of this study is to investigate the stable isotope composition of terrestrial mantle rocks (S, Te and Pd) and chondritic meteorites (Te and Pd) and to calibrate experimentally the stable isotope fractionation for the aforementioned elements imparted by metal-silicate equilibration during core formation. The measurements and experiments will constrain the geochemical behavior of S, Te, and Pd and their isotopes during core formation and may help to explain the observed isotopic differences between chondrites and bulk silicate Earth.
