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. |
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. |
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.

Righter et al. (2021) proposed that MET 96503, MET 96515, MET 01051, MET 01056, and MET 01057 are all paired and type L3.10. AMN 45, no. 2. |
