Writeup from MN J9(1):

Y-791834, 51-1

The section shows a microbreccia texture, composed of large coarse- and fine-grained clasts (up to) and angular fragments of pyroxene and plagioclase, set in a clastic matrix. Pyroxene compositions are widely scattered in low-Ca areas (Ca2Fe16 to Ca3Fe71) with exsolved blebs of high-Ca pyroxenes(Ca45Fe11 to Ca45Fe24). Plagioclase compositions are An79-86. One large cumulate eucrite clast (4 mm in diameter) contains pyroxene crystals with blebs of augite. The meteorite was previously classified as a polymict eucrite, but may be a howardite, because many pyroxene fragments appear to be opx).
