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
QUE 97632 - Cross-Polarized Light 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.
