The exterior has black fusion crust with fractures, abundant inclusions/chondrules of various sizes and colors and some oxidation. The interior is a dark gray matrix with abundant large and small inclusions/chondrules of various colors. |
This section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Fine-grained sulfides occur in the matrix. The texture appears more compact, though the origin of the compaction is unclear. Olivines range from Fa0.4-29 and pyroxene is Fs1. The meteorite is an unequilibrated CV3 chondrite. |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.7), and on Ni content of metal and sulfide and magnetic susceptibility (Oxidized A). Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
