30% of the exterior has thin brown/black patches of fusion crust. The interior matrix is dark gray in color and has a high metal content. Some areas reveal rusty patches. White, gray and rusty color chondrules/inclusions are visible within the matrix. |
The section exhibits large chondrules (up to 3 mm) and CAIs in a matrix of very fine-grained silicate and finely disseminated metal. The metal in the chondrules is more altered than the metal in the matrix (which can be described as small, but distinct grains). Olivines range from Fa4-11, and pyroxenes from Fs0-8Wo1-4, with on Wo49). The meteorite is a carbonaceous chondrite, probably a CV3, and possibly a reduced member of the CV3 group. |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.6), and on Ni content of metal and sulfide and magnetic susceptibility (Reduced). Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
