Achondrite (howardite)

History: A 145 g single stone with partial fusion crust was purchased in Erfoud, Morocco, in 2005.

Petrography: (J. Wittke and T. Bunch, NAU) Contains fine to medium cumulate basalt clast size (<3 mm diameter) and even finer-grained subophitic basalts (<1 mm) with diogenite fragments up to 8 mm.

Geochemistry: Cumulate basalt pyroxenes: Orthopyroxene (Fs49.4–64.7Wo2.1–2.5), exsolved pigeonite (Fs45.1–54.4Wo13.1–6.7), Ca pyroxene (Fs36.0–47.1Wo19.6–24.1). All pyroxene FeO/MnO = 29–34 (n = 27). Diogenite: Orthopyroxene (Fs26.7–30Wo2.2– 2.5; FeO/MnO = 24–30).

Classification: Achondrite (howardite); moderate weathering and low to moderate shock.

Specimens: A 21.4 g type specimen is on deposit at NAU. GHupé holds the main mass.
