V33A:
Chemical and Dynamical Constraints on the Formation and Evolution of the Terrestrial Planets II Posters


Session ID#: 10925

Session Description:
This session aims to bring together researchers studying the rates and processes that governed planetary accretion and differentiation. Such processes and timescales are still hotly debated. For example, how did chemical reservoirs evolve within the protoplanetary disk? What was the chemical composition of the material that accreted onto different bodies in the inner solar system? What was the nature and timing of volatile element depletion and addition to planets? What were the timescales planetary differentiation on Earth and other planets and planetesimals?

Topics of interest include efforts to determine the ages of early Solar System objects, the timing and sequence of volatile element depletion and addition to planets, as well as the chemical fingerprints left behind by crust, mantle, and core formation. We invite researchers that investigate these topics with both chemical and isotopic analysis of Earth and extraterrestrial materials as well as dynamical simulations of planetary formation processes.
