Impacts are a fundamental geologic process that has influenced the formation and modification of asteroids and planets throughout time. An important part of the impact history of the solar system is recorded in shocked meteorites. The asteroid Vesta has experienced large impacts, evidenced by two ~400-500 km impact structures that overprint the south pole region. While a range of shock-induced effects such as brecciation, melting and
the formation of maskelynite has been reported in howardite-eucrite-diogenite (HED) meteorites originating from
Vesta, high-pressure minerals have previously only been described in two eucrites [1-2]. Here, we present results on
an inventory of shock effects and high-pressure minerals preserved in the polymict eucrite NWA 10658
