Macroscopic Description - Cecilia Satterwhite
Exterior has black patches of fusion crust. Most of the exterior is gray with some evaporites. The interior is mottled gray with some darker gray areas and has a coarse grained texture.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
This section consist of ~50% of well-defined (up to 1 mm) chondrules and chondrule fragments set in a slightly recrystallized matrix of silicates and sulfides (both troilite and pentlandite). Olivines (Fs10) and pyroxenes (Fa38) are nearly homogeneous. The meteorite is an R chondrite, probably of petrologic type 4.
