The exterior of these carbonaceous chondrites has 5-30% black, patchy fusion crust. The black interior has mm-sized light gray and white chondrules. Some rust is visible. |
These meteorites were found within 2.5 km of each other and are so similar that a single description suffices. The sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa1-11, with many Fa1-5, and pyroxenes from Fs0-9. The meteorites are CV3 chondrites. |
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. |
