Genetic heritage of late accretion (B03)

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

Earth's water and volatile elements are thought to derive from the accretion of carbonaceous chondrite-like material from the outer solar system, but when, and how much, of this material was accreted by the growing Earth is debated. This project will use nucleosynthetic Mo and Ru isotope anomalies to determine the amount of carbonaceous chondrite-like material accreted by the Earth during distinct events in the final stages of Earth's growth before, during and after the Moon-forming impact. These data will provide new and firm constraints on the origin and composition of late-accreted materials, their relation to planetary building blocks, and the dynamics of the late stages of terrestrial planet formation.
