Macroscopic Description - Kathleen McBride
30% of the exterior has thin brown/black patches of fusion crust. The interior matrix is dark gray in color and has a high metal content. Some areas reveal rusty patches. White, gray and rusty color chondrules/inclusions are visible within the matrix.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy, and Linda Welzenbach
The section exhibits large chondrules (up to 3 mm) and CAIs in a matrix of very fine-grained silicate and finely disseminated metal. The metal in the chondrules is more altered than the metal in the matrix (which can be described as small, but distinct grains). Olivines range from Fa4-11, and pyroxenes from Fs0-8Wo1-4, with on Wo49). The meteorite is a carbonaceous chondrite, probably a CV3, and possibly a reduced member of the CV3 group.
