This 5.3-gram specimen is a verified piece of Rafsa 007, a plutonic Angrite. It serves as a prime example of alkali-depleted achondrites, distinguished chemically by a significant lack of sodium and potassium compared to other meteorite groups. The mineralogy features a specific high-temperature assemblage of Ca-rich olivine and Al-Ti diopside, providing a record of the specific magmatic conditions within the mantle of a differentiated planetesimal.
