Macroscopic Description - Kathleen McBride | |
The smooth, shiny brown-black exterior of this very fractured meteorite has oxidation haloes and a melted appearance. The interior is fine grained and rusty with no distinguishing characteristics. | |
Thin Section Description (,2) - Tim McCoy | |
The section exhibits numerous small (up to 1.2 mm), well-defined chondrules in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. polysynthetically twinned pyroxene is extremely abundant. Weathering is pervasive. Silicates are quite unequilibrated; olivines range from Fa4-31. A single pyroxene measured Fs27. The meteorite is probably an H3 chondrite and may be of relatively low subtype (~3.4). |
