Macroscopic Description - Kathleen McBride
The exterior surface is rusty gray with no fusion crust. The interior matrix is gray and rusty, containing large chondrules >3mm in size.
Thin Section Description (,2) - Cari Corrigan and Nicole Lunning
The sections consist of one round metal chondrule (~0.5 cm in diameter) and chondrule fragments. Chondrule fragments up to 1 mm are dominated by radiating pyroxene textures with olivine present. Silicates are magnesian (Fa3-15, Fs0-25Wo1-5). The meteorite is a CB chondrite and may be a member of the MIL 05082 pairing group.
