Macroscopic Description - | |
Overall color of the meteorite is metallic brownish-black with some reddish-brow) due to the oxidation of the iron. The S half of the B surface was in contact with the ground at time of recovery. This surface (B) ranges in color from yellowish brown to reddish-brown. The specimen is irregular in shape, ~28 x 23 x 14 cm, and has many regmaglypts. The regmaglypts on the B surface have greater relief than those on the T surface. The W surface is smoother than the rest of the specimen. The B-S surface is partially covered by what appears to be an evaporite deposit. Several small laths of schreibersite (?) are present on the sample. | |
