95% of the exterior is covered with brown/black fusion crust with small shiny patches. The rusty, granular interior has mm sized black inclusions and green mineral grains that are up to 2 mm in size. |
These two small sections are unbrecciated rocks dominated by orthopyroxene (Fs25Wo3), olivine (Fa30) and plagioclase (An80-85Or1). Most grains are less than 0.5 mm in diameter, although a single pyroxene in 031381 reaches 4 mm. The meteorites are unbrecciated olivine diogenites. |
