Sample No.: QUE94613
Location: Queen Alexandra Range
Dimensions (cm): 2.0 x 1.5 x 1.0
Weight (g): 5.1
Meteorite Type: Ureilite

Macroscopic Description: Kathleen McBride

Forty percent of the exterior of this meteorite is covered with dark brown to black fusion crust. Areas without fusion crust are rusty brown in color. The interior is dull brown to black with some metal grains and some weathered mineral grains visible.

Thin Section (,2) Description: Brian Mason

The section shows anhedral grains of olivine and a little pyroxene (grains up to 2.4 mm across) in a black matrix. The matrix contains veinlets of brown limonite, presumably from the weathering of metal and sulfide. Microprobe analyses show olivine of nearly uniform composition, Fa22-24, with notably high CaO (0.4%); pyroxene composition is Wo10Fs19. The meteorite is a ureilite; it appears to be relatively unshocked compared to most ureilites. It is probably paired with QUE93336 and 93341.
