Thin Section Description (,2) - Cari Corrigan, Tim McCoy
These sections are similar enough that one description suffices. The sections consist of ~50% distinct chondrules (up to 1 mm) and chondrule fragments set in a slightly recrystallized matrix of silicates, sulfides and chromite. Olivine compositions are Fa12-47 with most at Fa39, while pyroxenes range from Fs2-25. The meteorites are heavily shocked. The meteorites are R chondrites and may be associated with the PRE 95404 pairing group.
