Wittke, NAU): an unusual howardite that contains an array of plastically deformed shocked eucrite and diogenite clasts. Shock characteristics range from crushed cataclastics (S2-4), maskelynite-bearing (S4), recrystallized pyroxenes and plagioclase (S5) to melt clasts (S6) that contain olivine as the quenched mafic phase in place of typical pyroxenes.
