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, 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. |
