Weight (g):	22.433
Meteorite Type:	L3 Chondrite

Macroscopic Description: Kathleen McBride
90% of this ordinary chondrite's exterior has brown/black fusion crust with oxidation haloes. The interior is a gray matrix with high metal content and numerous gray and white chondrules.

 

Thin Section (,2) Description: Tim McCoy, Lauren LaCroix and Linda Welzenbach
The section exhibits numerous large, well-defined chondrules (up to 3 mm) in a black matrix of fine-grained silicates, metal and troilite. Strong shock effects are present. The meteorite is moderately weathered. Silicates are unequilibrated; olivines range from Fa_8-25, with most grains Fa_20-22, and pyroxenes from Fs_4-19. The meteorite is an L3 chondrite (estimated subtype 3.8).
