The exterior has fractured brown/black fusion crust with evaporites. Flow lines are visible on one surface. Areas without fusion crust are weathered brown with some gray/black matrix visible. Some rusty areas are visible. The interior is a dark gray to black matrix with heavy oxidation and rusty areas. Metal is visible and this ureilite was very difficult to break. |
The section consists of an aggregate of large (up to 2.5 mm) olivine grains. Individual olivine grains are rimmed by carbon-rich material containing traces of metal. Metal forms veins between olivines. Olivine has cores of Fa22. Pigeonite grains have compositions of Fs11-18 and Wo5-11. The meteorite is a ureilite. |
