Classification: HED achondrite (Eucrite, monomict)
Petrography: (A. Irving and S. Kuehner, UWS): Ophitic-textured assemblage of calcic plagioclase laths and exsolved pigeonite blades accompanied by relatively large grains of silica polymorph, chromite (of variable Ti content), ilmenite and rare zircon. Exsolved pyroxenes have either coarse lamellae of clinopyroxene in an orthopyroxene host, or lamellae of orthopyroxene in a clinopyroxene host. Plagioclase contains abundant microscopic blebs of exsolved orthopyroxene.
Geochemistry: Orthopyroxene (Fs59.1-59.6Wo4.6-5.1, Fe/Mn=29.7-31.6), clinopyroxene (Fs29.1-29.3Wo40.3-40.7, Fe/Mn=31.3-32.7), plagioclase (An88.2-89.7Or0.7). Oxygen Isotopes (D. Rumble, CIW): acid-washed material analyzed by laser fluorination gave, respectively d18O = 3.63, 3.58; d17O = 1.66, 1.63; ?17O = -0.251, -0.253 per mil.
