Exterior is covered with shiny, very dark brown varnish and has some orange weathering spots. Fresh interior is black with some small, round, light orange-brown inclusions (<1mm) and has orange rust throughout. |
These sections are similar enough that a single description is given, although a more detailed description is warranted. These sections exhibit large chondrules (up to 3 mm) with refractory inclusions and amoeboid olivine aggregates in a dark matrix. Metal and sulfide are common in these meteorites, including a ~3 mm irregularly shaped particle in MIL 15148. Olivines range from Fa1-31, with most Fa1-5, and pyroxenes from Fs1-3. The meteorites are unequilibrated and appear to be carbonaceous chondrites, probably reduced CV3s.

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. |
