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. |
Righter et al. (2021) proposed that MET 00489, MET 01211 and MET 01322 are all paired and type L3.6. MET 00621 was removed from this pairing group and instead paired with MET 00452 and MET 00526. AMN 45, no. 2. |
