Exterior has a black fusion crust with brown oxidation. Exposed interior reveals inclusions/chondrules with some rust and oxidation. Grayish brown interior is weathered with some rusty oxidation. Clast and inclusions are gray, white and weathered. |
The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa1-25. 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. |
