Is the composition of the Earth skin deep?
The bulk composition of Earth is commonly assumed to be chondritic but evidence from measurements of isotopic ratios in rocks on Earth suggests that it differs significantly from that of chondritic meteorites. In this talk we suggest that erosive collisions during the formation of the Earth may be to blame. We will begin by presenting our state-of-the-art collision model then move on to discuss our preliminary results and conclude by extending our results to extrasolar systems.
