| Macroscopic Description - Kathleen McBride | |
| The exterior is covered with 100% brown/black fusion crust with polygonal fractures. The interior is a black fine grained matrix with light colored inclusions. The meteorite is moderately hard. | |
| Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach | |
| The section consists of abundant (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 Fa0-44 and pyroxenes range from Fs1-3. This meteorite is a CO3 chondrite and is possibly paired with DOM 08004 pairing group. | |
| Reclassification Notes (AMN 34,1) | |
| Removed several pairing group members (DOM 10121, DOM 10299, DOM 10847, and DOM 14359) based on petrography, CRE ages, Cr contents of olibvine, and H, C and N bulk and isotopic compositions.
