Macroscopic Description: Kathleen McBride
Brown/black slightly rough fusion crust covers 90% of this ordinary chondrite’s exterior. The interior is a dark gray matrix with rust and high metal content. Some light chondrules are visible.

 

Thin Section (,2) Description: Tim McCoy, Linda Welzenbach and Cari Corrigan
The section exhibits numerous closely-packed, well-defined, small (up to 1 mm) chondrules in a black matrix of fine-grained silicates, metal and troilite. Modest shock effects and weathering are present. Silicates are unequilibrated; olivines range from Fa9-30 and pyroxenes from Fs3-23. The meteorite is an H3 chondrite (estimated subtype 3.6).
