| The exteriors of these paired meteorites are covered with brown/black smooth fusion crust. The interiors are a rusty black to gray color with high metal content and chondrules of various sizes and colors. |
| The sections exhibit numerous large (up to 2 mm), well-defined chondrules in a dark matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is abundant. The meteorites are lightly weathered. Silicates are unequilibrated; olivines range from Fa8-40, with a large peak at Fa28-30, and pyroxenes from Fs14-24. The meteorites are LL3 chondrites, probably of subtype ~3.8. |
| Classification updated to LL3.8 as announced in AMN 31 no. 2. |
