Macroscopic Description - | |
The T surface of the meteorite was in contact with the ice at the time of recovery. The sample has some consolidated soil on this surface, which is brownish-yellow. The overall color of the sample, ~7.5 x 6.5 x 3.0 cm, is metallic brown. The S half of the B surface is smooth and silverish-brown, while the N half of the B surface is characterized by a silverish material that has slightly more relief than the back round and could possibly be schreibersite (?), cohenite (?), daubreelite (?). This material with higher relief rings the outer edge of most of the regmaglypts. | |
