Writeup from AMN 8(1):
Sample No.: EET83283 Location: Elephant Moraine Weight (g): 57.2 Field No.: 1320 Dimensions (cm): 6 x 2.5 x 3 Meteorite Type: Polymict Eucrite
Macroscopic Description: Roberta Score This eucrite is typical of the other 1983 Elephant Moraine eucrites.
Thin Section (,3) Description: Jeremy Delaney A typical polymict achondrite with lithic and mineral clasts similar to other Elephant Moraine polymict eucrites. Some pyroxene clasts appear to be shocked orthopyroxene (En55-65) but most are pigeonitic with fine exsolution. None are as magnesian as diogenitic pyroxene. Lithic clasts are generally fine-grained basalts and breccia clasts. The matrix of this section is very dark and full of holes and cracks suggesting that it has been severely weathered. Specimen is generally similar to EETA79004 and 79011. | ||||||||||||||||||||
