Sample No.:
QUE93723
Location:Queen Alexandra Range
Dimensions (cm):2.8 x 2.1 x 1.3
Weight (g):15.4
Meteorite Type:Howardite
Macroscopic Description: Cecilia Satterwhite
Black patches of fusion crust cover thirty percent of the exterior of this achondrite. Areas without fusion crust are greenish gray and some small white inclusions are visible. The interior surface reveals a mottled gray color with abundant small white and dark inclusions. Minor oxidation is scattered throughout the sample. The white plagioclase inclusions are 1-2 mm in size. The darker inclusions are smaller. The meteorite has a medium grained texture.

Thin Section (,3) Description: Brian Mason
The section is a microbreccia of pyroxene with minor plagioclase, and a few minute opaque grains. Individual clasts range up to 1.8 mm across. Microprobe analyses show that pyroxene compositions range fairly uniformly from Wo2Fs22 to Wo15Fs50; plagioclase compositions range from An80 to An94. One grain of SiO2, probably tridymite, and one grain of ilmenite were analyzed. The meteorite is classified as a howardite.
