Geochemistry and petrology of howardite Miller Range 11100: A lithologically diverse piece of the Vestan regolith
Abstract The howardite‐eucrite‐diogenite ( HED ) clan of meteorites, which most likely originate from the asteroid Vesta, provide an opportunity to combine in‐depth sample analysis with the comprehensive remote‐sensing data set from NASA 's recent Dawn mission. Miller Range ( MIL ) 11100, an An...
