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: Wo_5-10, Fs_28-49, but a few Ca-rich grains are present, up to Wo₄₃Fs₂₅. Plagioclase compositions are An_82-87. 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.
