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. |
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. |
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. |
