| Macroscopic Description - Rachel Funk, Cecilia Satterwhite | |
| The exteriors of these paired meteorites have black/brown fractured fusion crust with weathered areas and evaporites. The interiors are a dark gray to black matrix with some white specks, abundant in some areas and some large white inclusions. Some areas are rusty and weathered. | |
| Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
| These 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 Fa1-56. Pyroxene analyses range from Fs1-62Wo0-2. The meteorites are CO3 chondrites, probably paired with the DOM 08004/DOM 10101 pairing group. | |
| Reclassification Notes (AMN 44,2) | |
| In vol. AMN 44, no. 2, we removed several pairing group members (DOM 10121, DOM 10299, DOM 10847, and DOM 14359) based on petrography, CRE ages, Cr contents of olivine, and H, C and N bulk and isotopic compositions.
