Writeup from MN J7(1):

Y-791195, 91-2: Eucrite (unbrecciated)

          Unbrecciated, eucrites with medium-grained, granular pyroxene and plagioclase. Rare subrounded grains of opaque mineral (chromite) poikilitically enclose silicates. White plagioclase regions consist of much smaller polygonal, occasionally rounded crystals. Veins with much fine-grained silicates can be recognized. Because of slightly more Mg-rich chemistry of pyroxene, Y-791195 was classified as a cumulate eucrite, but it may a metamorphosed ordinary eucrite, which have suffered from extensive recrystallization by metamorphic events.
