Writeup from AMN 19(1):
Sample No.:QUE94484
Location:Queen Alexandra Range
Dimensions (cm):2.5 x 2.0 x 0.8
Weight (g):5.6
Meteorite Type:Eucrite (unbrecciated)
Macroscopic Description: Kathleen McBride
QUE94484 is a complete button-shaped stone. The fusion crust is dull brownish-black. The interior consists of dark gray crystalline material, some appearing as laths. Patches of heavy rust are present.

Thin Section (,2) Description: Brian Mason
The section shows an aggregate of plagioclase laths (up to 1.3 mm long) and anhedral pale brown pyroxene grains; interstitial to the plagioclase and pyroxene are angular areas of fine-grained black material. The section is partly rimmed with fusion crust. Microprobe analyses show that most of the pyroxene is low-Ca: Wo5-10, Fs28-49, but a few Ca-rich grains are present, up to Wo43Fs25. Plagioclase compositions are An82-87. The fine-grained black areas consist largely of troilite and tridymite, suggestive of a quenched residual liquid. The composition of the fusion crust, probably similar to that of the bulk meteorite, is (weight percent): SiO2 50, Al2O3 13, FeO 17, MgO 6.5, CaO 11, TiO2 1.0, MnO 0.55, Na2O 0.80, K2O less than 0.1. The meteorite is an unbrecciated eucrite.
