Macroscopic Description: Kathleen McBride
Polygonally fractured, vesicular, black fusion crust totally covers QUE94582. The medium gray interior has a few white inclusions scattered throughout.

Thin Section (,2) Description: Brian Mason
The section shows numerous small grains of olivine and pyroxene and a few chondrules (up to 0.6 mm across) in a matrix which is partly black and opaque and partly pale green and isotropic. Trace amounts of nickel-iron and troilite are present in the matrix. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa_2-31; pyroxene, Fs_1-20. The meteorite is classified as a C2 chondrite.
