A Pyroxenite Mantle on Mercury? Experimental Insights from Enstatite Chondrite Melting at Pressures up to 5 GPa
Asmaa Boujibar, Kevin Righter, Emmanuel Fontaine +4
Enstatite chondrites (EC) are potential source material for the accretion of Mercury due to their reduced nature and enrichment in volatile elements. Understanding their melting pr…
