Weight (g):	0.798
Meteorite Type:	Eucrite (Brecciated)

Macroscopic Description: Kathleen McBride
100% of the exterior of this achondrite is covered by brown/black fusion crust with oxidation halos. The interior is a dark gray matrix with minor rust. Light gray clasts are visible and range in size from 1-2 mm in diameter.

Thin Section (, 2) Description: Tim McCoy
The section contains a fine-grained (~50 micron average grain size) brecciated matrix with ophitic clasts up to 1 mm in diameter with grain sizes ~300 microns. Mineral compositions are homogeneous with orthopyroxene (Fs₆₁Wo₂), with lamellae of augite (Fs_>27Wo₄₄), and plagioclase (An₈₁Or). The Fe/Mn ratio of the pyroxene is ~30. The meteorite exhibits significant shock effects, including shock veins. The meteorite is a brecciated eucrite.
