Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components
Meteoritics &Planetary Science, EarlyView.Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...
