Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...
