Y-791960, 91-2

This section is a polymict pyroxene-plagioclase breccia, with numerous mafic lithic clasts in addition to mineral clasts. However, the section differs in texture from most other Yamato polymict eucrites, in that it does not contain large mesostasis-rich basaltic clasts. Common eucrite clasts are granulitic and are similar to some ordinary eucrite clasts in howardites. Magnesian (diogenitic) orthopyroxenes are not common, but more abundant (2 to 7 vol %) than in the polymict eucrites. The presence of large diogenitic pyroxene (0.66 ยด 0.48 mm) and cumulate eucrites are rather similar to howardite. This meteorite is a polymict eucrite with minor howardite components.
