The exterior is covered with brown/black shiny fusion crust with pits, evaporites and oxidation haloes. The interiors consist of a gray and black matrix with tiny light inclusions. |
These sections are so similar that a single description suffices. The sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa1-62, with a continuous range of intermediate compositions and a slight peak at Fa20-40. Two pyroxene analyses range from Fs1-8Wo2-4. The meteorites are CO3 chondrites. |
