Writeup from AMN 19(1):
Sample No.:QUE94570
Location:Queen Alexandra Range
Dimensions (cm):5.0 x 3.6 x 1.8
Weight (g):57.2
Meteorite Type:C4 chondrite
Macroscopic Description: Roberta Score
Thin, extremely weathered, iridescent fusion crust remains on half of this angular specimen. Black weathered material makes up the interior. Small, silver-colored blebs of sulfides are scattered across the broken face. Evaporite deposit is present.

Thin Section (,2) Description: Brian Mason
The section shows a close-packed aggregate of chondrules, up to 2.4 mm across, in a small amount of dark matrix. About 20% of the nickel-iron and troilite is present, much of it rimming the chondrules. Weathering is extensive, with veins of brown limonite throughout the section. Microprobe analyses show olivine and pyroxene of fairly uniform composition: olivine, Fa10-13, Fs9-12. This meteorite is very similar to Coolidge (Meteoritics, v. 30, p. 20, 1995), and is tentatively classified as a C4 chondrite.
