Macroscopic Description: Kathleen McBride
CMS 04044 has a fractured brown exterior. 048 has 60% dull brown/black fusion crust with some polygonal fractures and oxidation. The interiors are rusty, crystalline with fractures. 044 has evaporites present.

Thin Section (,2 ,4) Description: Tim McCoy
The meteorites are so similar that a single description suffices. The sections consist of an aggregate of large olivine and pyroxene grains up to 2 mm across. Individual olivine grains are rimmed by carbon-rich material containing traces of metal. Olivine has cores of Fa23, with rims reduced to Fa3. Pigeonite is Fs19, Wo7. The meteorites are ureilites.
