Macroscopic Description - Kathleen McBride
40% of the surface has a black fusion crust and exhibits both dull and shiny areas. The fusion crust has polygonal fractures and evaporites. The interior matrix is brown and weathered with vague appearing chondrules.
Thin Section Description (,2) - Cari Corrigan and Linda Welzenbach
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments, a few CAIs (up to 2 mm) and mineral grains in a dark matrix. Metal and sulfide occur within the chondrules and in the matrix. Olivine ranges in composition from Fa0-73. One pyroxene analysis is Fs1Wo43. The matrix appears to consist largely of Fe-rich olivine. Terrestrial weathering effects are moderate. The meteorite is a CO3 chondrite.
