Macroscopic Description: Kathleen McBride
The exterior of this meteorite has a dull black fusion crust with iridescent oxidation halos covering about 70% of its surface area. It is heavily fractured and is friable. The interior consists of dull, black matrix with numerous dark inclusions and yellow, cream and white chondrules, some up to 2 mm in diameter. The meteorite is weathered in some areas.

Thin Section (,2) Description: Tim McCoy
EET96259 - Cross-Polarized Light The section exhibits large well-defined chondrules (up to 2 mm) and metal in a dark matrix. Clasts of C1-like material are present. Polysynthetically twinned pyroxene is abundant. Weathering is pervasive, with alteration of metal and extensive staining of silicates. Silicates are unequilibrated; olivines range from Fa0-4 and pyroxenes from Fs1-4. The meteorite is probably a CR2 chondrite.
