Macroscopic Description: Kathleen McBride
Patches of thin brown and black fusion crust remain on this small weathered stone. The weathered black interior has areas of heavy oxidation.

Thin Section (,2) Description: Brian Mason
The section shows a close-packed aggregate of chondrules (up to 1.8 mm across) and chondrule fragments in a black matrix containing some troilite and nickel-iron. The section is partly rimmed with fusion crust. Weathering is extensive, with limonitic staining and patches of brown limonite throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine Fa_6-29, mean Fa₁₆; pyroxene, Fs_3-15. The meteorite is classified as an L3 chondrite (estimated L3.4).
