| Macroscopic Description - Cecilia Satterwhite | |
| Black/brown fusion crust covers 50 % of the exterior surface. The interior is dark gray to black with abundant clasts. Some as large as ½ cm are visible. | |
| Thin Section Description (,2) - Linda Welzenbach, Tim McCoy | |
| The section exhibits numerous large, well-defined chondrules (up to 3 mm) in a matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Olivines range from Fa13-45; pyroxenes from Fs1-18. This meteorite contains a fine-grained clast with uniform mineral compositions (Fa32,Fs23). The origin of this clast and its relationship to the host is uncertain, but may be impact-related. The meteorite is a L3 chondrite (estimated subtype 3.6). This meteorite may be paired with the MET 00489 pairing group. | |
