Sample No.: EET83225 Location: Elephant Moraine Weight (g): 44.0 Field No.: 2798 Dimensions (cm): 5 x 2.5 x 2.5 Meteorite Type: Ureilite
Macroscopic Description: Roberta Score The fusion crust on this ureilite is very thin. The exterior surfaces are smooth and have a dull sheen. The overall exterior color is brownish-black. Crystalline grains with well-developed crystal faces make up the interior. Most of the center of this achondrite is heavily oxidized giving it a reddish-brown color.
Thin Section (,6) Description: Jeremy Delaney Medium to coarse-grained ureilite with clean crystals of olivine and pyroxene. Thin section is pyroxene-rich with 120° triple junctions being quite common. Grain boundaries coated with dark material containing vein-like metal, graphite and yellow/red cathodoluminescent phase; probably diamond. Tiny metallic inclusions also occur in some pyroxene and olivine grains. Thin section shows a clear dimensionally-dependent preferred orientation of both pyroxene and olivine suggesting cumulus texture. Olivine is Fo87-92 and pyroxene is pigeonite En78-79Wo10.5. | ||||||||||||||||||||
