Macroscopic Description: Kathleen McBride
Most of the fusion crust on this meteorite has weathered away. The little that remains is thin, rough, black patches with iridescent oxidation halos. The interior is a dark matrix with numerous, multicolored chondrules, gray, white, tan and yellow, some are larger than 1 mm. There are metal grains present and minor rust.

Thin Section (,2) Description: Tim McCoy
EET96109 - Cross-Polarized Light The section exhibits numerous large, well-defined chondrules (up to 1.6 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Glass is present within chondrules, but rare. Polysynthetically twinned pyroxene is extremely abundant. Silicates are quite unequilibrated; olivines range from Fa0-19 and pyroxenes from Fs3-26. The meteorite is probably an LL3 chondrite and may be of relatively low subtype (<3.4).
