Thin Section Description (,2) - Cari Corrigan, Tim McCoy
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.
