Writeup from AMN 17(3):
Sample No.: QUE93008
Location: Queen Alexandra Range
Dimensions (cm): 1.5 x 1.5 x 0.7
Weight (g): 2.9
Meteorite Type: Howardite

Macroscopic Description: Cecilia Satterwhite
One patch of black fusion crust remains on this achondrite. One large black inclusion which measures approximately 4 x 2 mm is visible on the exterior surface. The interior is a lighter gray than the exterior and contains numerous 1-2 mm, light and dark inclusions. A minor amount of oxidation is present.

Thin Section (,3) Description: Brian Mason
The section shows a brecciated texture, with angular clasts of pyroxene and plagioclase, up to 0.9 mm across, in a fine-grained comminuted groundmass of these minerals. Microprobe analyses show two distinct pyroxene compositions: orthopyroxene of fairly uniform composition, averaging Wo2Fs25, and pigeonite of variable composition, Wo5-15, Fs40-50. Plagioclase composition ranges from An87 to An94. The presence of the orthopyroxene component indicates that the meteorite can be classified as a howardite.
