| Macroscopic Description - Kathleen McBride | |
| Fusion crust covers 10% of the exterior which has a ropy, purplish black color. The interior is a black matrix with gray and white chondrules/clasts. | |
| Thin Section Description (,2) - Tim McCoy, Linda Welzenbach | |
| The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa1-32 and pyroxenes from Fs0-2. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3. | |
