Macroscopic Description - | |
This irregular shape specimen is dark metallic reddish-brown. The B surface was touching the ground when the meteorite was recovered, this surface is yellowish-brown and highly oxidized. The T surface is covered with regmaglypts. The bottom of a few of these regmaglypts is stained by orangish-brown iron oxidation. The S & W surfaces are wider than the N & E surfaces. The sample is ~22 x 20 x 15 cm. | |
