The exterior of this ordinary chondrite is covered completely with smooth, shiny fusion crust, exhibiting numerous oxidation halos. The interior is mostly rust with abundant metal. There are mm-sized chondrules that are stained with rust and appear as small specks. This meteorite is very hard. |
The section exhibits numerous well-defined chondrules (most ~0.5 mm in diameter), metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is abundant. Weathering is pervasive, with extensive staining. Silicates are unequilibrated; olivines range from Fa9-23 and pyroxenes from Fs1-25. The meteorite is probably an H chondrite of subtype ~3.6. |
