Macroscopic Description: Kathleen McBride
100% of the exterior is covered by brown/black fusion crust with oxidation haloes. The interior is a rusty black matrix with gray chondrules and a high metal content.

 

Thin Section (,2) Description: Tim McCoy, Lauren LaCroix and Linda Welzenbach
The section exhibits numerous well-defined chondrules of a range of sizes (up to 2.6 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects and weathering are present. Silicates are unequilibrated; olivines range from Fa_1-20 and pyroxenes from Fs_1-6. The meteorite is an H3 chondrite (estimated subtype 3.4).
