Macroscopic Description - Cecilia Satterwhite

Exterior has black/brown fractured fusion crust with oxidation. Areas without fusion crust reveal a black matrix with light inclusions/chondrules. The interior is very similar to DOM 19170, black matrix with oxidation and light/weathered inclusions/chondrules. Some evaporites are present.

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

The sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments, CAIs, and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa_0-60. Pyroxene analyses range from Fs_0-33. Terrestrial weathering effects are modest. Meteorites are similar enough that one description suffices, and they are likely paired. The meteorites are CO3 chondrites and may be members of the larger Dominion Range CO3 pairing group (named for DOM 08004).
