Diogenite |
| Macroscopic Description - Kathleen McBride |
| 50% of the exterior is covered by dark brown black fusion crust with polygonal fractures. The exposed interior is tan and fractured. The tan interior with yellowish brown patches mars the surface. Black, glassy veins and inclusions and a few white clasts are present. |
| Thin Section
(,4) Description - Tim McCoy and Linda Welzenbach |
| The section shows a groundmass of coarse (up to 2 mm) comminuted pyroxene with interstitial plagioclase and SiO2. Orthopyroxene has a composition of Fs27-34 Wo1-4 and plagioclase is An85-89Or1 . The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a diogenite, although the pyroxene is on the FeO-rich end of diogenites towards cumulate eucrites. |
