The exterior is covered with fractured brown/black fusion crust with a rough texture. Exposed areas without fusion crust are dark gray to black in color with some oxidation. The interior is a dull gray to black matrix with a few lighter inclusions and oxidation. |
The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa1-32. The meteorite is an unequilibrated CV3 chondrite. |
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. |
