The section consists mostly of an aggregate of large pyroxene grains up to 2.5 mm across with some smaller olivines. Individual olivine and pyroxenes grains are rimmed by carbon-rich material containing traces of metal. Olivines have compositions of Fa22. Pigeonite (Fs18,Wo10) grains exhibit irregular lamellae. The meteorite is a ureilite. |
