50% of the exterior surface has patches of fusion crust, that exhibit polygonal fractures and evaporites. The interior matrix is black with a light gray oxidation rind and light inclusions. |
The section exhibits large chondrules (up to 2 mm) and CAIs in a dark matrix. The section is moderately weathered. Olivines range from Fa0-94, and pyroxene is Fs48Wo51. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3. |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.6), and on Ni content of metal and sulfide and magnetic susceptibility (Oxidized B). Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
