| The exterior is covered with 80% black fusion crust. Some areas are weathered brown with visible chondrules. The interior is heavily weathered with some dark gray to black matrix visible. The visible chondrules/inclusions are weathered. |
| The section exhibits numerous well-defined chondrules (up to 1 mm) in a matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is abundant. The meteorite is modestly stained with hydrated iron oxides of terrestrial origin. Silicates are unequilibrated; olivines range from Fa4-27 and a pyroxene is Fs19. The meteorite is an LL3 chondrite (estimated subtype 3.8). |
