The fusion crust on these paired meteorites ranges from none to 20% purplish black with fractures. The interiors range in colors from brown to gray to black with evaporites. Abundant multicolored chondrules are visible. |
The sections 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 Fa0-9 and low-Ca pyroxene is Fs1-2. The meteorites are unequilibrated carbonaceous chondrites, probably CV3. |
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. |
