Some of the exteriors have black patches of fusion crust, some have fractures and evaporites. The interiors range from a gray to black matrix with moderate to heavy oxidation. All have abundant mm sized inclusions and chondrules in various colors. |
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 Fa0-43 and low-Ca pyroxene from Fs1-5. The meteorites are unequilibrated carbonaceous chondrites, probably reduced CV3. These are likely paired with the MIL 07590 pairing group previously reported. |
Reclassification and pairing based on magnetic susceptibility and location proximal to other CV Oxidized A 3.7 from the middle MIL icefield. Details are reported in Righter et al. (2022); doi: 10.1111/maps.13932. |
