Kuehner, UWS): polycrystalline clasts include basaltic eucrite (ophitic texture, variable grain size, mainly anorthite + pigeonite Wo16Fs57, FeO/MnO = 30); cumulate eucrite (coarse grained, equigranular, mainly anorthite + exsolved pigeonite with accessory silica); rare eucritic breccias and distinctive ferroan intergrowths (fayalite + hedenbergite + silica ± troilite). Mineral clasts include homogeneous pigeonite grains (Wo15Fs31, FeO/MnO = 26), pigeonite grains with clinopyroxene exsolution lamellae (FeO/MnO = 30–33), anorthitic plagioclase (Ab6-Ab10) and a silica polymorph. Accessory minerals in clasts and matrix include ilmenite, Fe metal, chromite, baddeleyite and apatite. Specimens: type specimen, 20 g, and four polished thin sections, UWS; main mass, Hupé.
