A large proportion of the exterior of this 9.0 x 6.0 x 6.0 cm sample is weathered and stained by iron oxidation and spotted with small patches of black fusion crust. Except for the inner most material, this sample is totally weathered. The light matrix material of the inner most material is spotted with iron-oxidation and contains many small (as great as 3 mm in maximum diameter) dark clasts.
