DEW96601 Thumbnail

Macroscopic Description: Kathleen McBride
The exterior has brown/black fusion crust with oxidation halos and some evaporites. The interior has a sugary texture with rusty metal grains. Dark and light colored chondrules are visible and some rusty inclusions are present.

Thin Section (,2) Description: Tim McCoy
DEW96601 - Cross-Polarized Light The section exhibits numerous small, well-defined chondrules (up to 1 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Weathering is pervasive. Silicates are unequilibrated; olivines range from Fa14-21 and pyroxenes from Fs3-17. The meteorite is probably an H3 chondrite (estimated subtype 3.8).
