Y-791192, 91-3: Eucrite

(unusual breccia of cumulae eucrites and one ordinary eucrite?)

          Small angular to subangular fragments of pyroxene and minor plagioclase, are set in dark glassy matrix. Sizes of the fragments are fairly uniform except for one eucritic lithic clast. This clast show dark fine-grained variolitic texture of brown pyroxene and white plagioclase. This breccia is similar to Y-75032-type achondrite, especially to Y-791439, but contains an unusual eucritic clast and less diogenitic components as in Y-75032. Unusual howardite or polymict eucrite with affinity to Y-75032.
