Writeup from AMN 8(1):
Sample No.: EET83228 Location: Elephant Moraine Weight (g): 1206.0 Field No.: 2862 Dimensions (cm): 12.5 x 11.5 x 8.5 Meteorite Type: Polymict Eucrite
Macroscopic Description: Roberta Score One small patch of black fusion crust remains on EET83228. Fracturing is moderate. The exterior surfaces are darker gray than the interior surfaces. There are many areas that are heavily oxidized. Numerous deep vugs are present on all exterior surfaces. Clasts of different types are abundant. This stone is similar to other 1983 Elephant Moraine eucrites.
Thin Section (,4) Description: Jeremy Delaney A polymict achondrite breccia with a few small lithic clasts. These lithic clasts have the variety of textures seen in mafic clasts from howardites and polymict eucrites varying from medium-coarse granular clasts to interstitial basalts. A few large orthopyroxene clasts have concentric zoning (cores are En70-75) suggesting exchange reactions with the surrounding breccia are present. These modified pyroxene clasts are similar to clasts in EETA79004 with which this sample may be paired. | ||||||||||||||||||||
