Black/brown fusion crust covers the exterior of this carbonaceous chondrite. The fusion crust has a vesicular and fractured appearance. Minor orange rust is present. The interior is a black matrix with 1-2 mm sized chondrules. Minor rust is visible. |
This section exhibits large chondrules (up to 2.5 mm) and CAIs in a dark matrix. Olivines range from Fa0-5 and pyroxenes from Fs3. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3. |
Reclassification and pairing based on Raman spectroscopy (petrologic type 3.7), 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. |
