Characterization of carbon phases in Yamato 74123 ureilite to constrain the meteorite shock history 

The formation and shock history of primitive achondrites meteorites such as ureilite has been debated for decades! The characterization of carbon phases can provide pivotal information on diamond and graphite formation in ureilites thus shedding light on the origin and history of these meteorites. In this work, Anna Barbaro and co-authors present X-ray diffraction and micro-Raman spectroscopy analyses performed on diamond and graphite occurring in the ureilite Yamato 74123 (Y-74123).
