| Macroscopic Description - Cecilia Satterwhite | |
| These ordinary chondrites have a dark gray to black matrix with oxidation scattered throughout. Gray, white and cream colored (mm to ½ cm sized) inclusions are visible. Some areas are rusty brown. | |
| Thin Section Description (,2) - Linda Welzenbach, Tim McCoy | |
| These meteorites are so similar that a single description suffices. The sections exhibit 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 Fa1-35; pyroxenes from Fs2-25. The meteorites are L3 chondrites (estimated subtype 3.6). These meteorites are very likely paired with MET 00489 and MET 00621. | |
| Reclassification Notes (AMN 44,2) | |
| Reclassified as an L3.10 Chondrite based on Cr contents of Type II chondrule olivine. Pairing groups adjusted based on olivine composition and recovery location.
