Title: Mode of terrestrial planet formation and heritage of Earth’s volatiles: the story from isotope anomalies in meteorites
Abstract: As tracers of planetary genetics, isotope anomalies among planetary materials can provide key constraints for unraveling the Solar System’s dynamical evolution, from the collapse of the molecular cloud to the formation of the terrestrial planets. In this lecture I will show how isotope anomalies among meteorites can be used to constrain the origin of Earth’s and Mars’ building blocks, and whether pebble accretion or the classic oligarchic growth regime dominated the accretion of the terrestrial planets in the solar system. Further, I will briefly discuss why it is relevant to know what the Earth is made of in the first place, and end with some reflections on what isotope anomalies tell us – and what they don’t tell us – about the origin of Earth’s volatiles.
