Macroscopic Description - Kathleen McBride
The exterior is covered with 80% black/brown fusion crust. The interior is a rusty black, fine grained matrix with high metal content.
Thin Section Description (,2) - Cari Corrigan and Linda Welzenbach
The section consists dominantly of individual clasts containing shocked chondrules, as well as chondrule fragments. Clasts exhibit moderate shock effects. Metal sulfide melt textures are present, with most of the metal found within the veins between clasts. Veins are, for the most part, completely opaque. Olivine compositions are Fa24-29 and pyroxene is Fs20. The meteorite is an impact melt breccia of an L chondrite precursor.
