Wittke, NAU): a howardite of unusualcharacteristics. Fine-grained and powdery, average clast and mineral grain sizeis < 2 mm with few clasts > 3 mm. Clast modes: diogenites, 74 vol. %;eucrites 20 vol. % (12 % cumulate, 8 % basaltic); anorthositic-like clasts, 3%; shock melt clasts. 2 %, and opaques, 1%. Diogenite orthopyroxene, Fs35.6-38.8Wo2.3-4.2;plagioclase, An 87; chromite, Cr/(Cr+Al) = 0.81; metal, Ni = 0.67 wt%.
