Dimensions (cm): 7.5 x 7.5 x 3

Meteorite Type: Polymict Eucrite

 

Macroscopic Description: Roberta Score

EET83234 is a fragment that is similar to other 1983 Elephant Moraine eucrites. This stone contains a corner of a brown crystalline clast similar to that in EET83229 and may, in fact, actually be a piece of EET83229.

 

Thin Section (,3) Description: Jeremy Delaney

Typical polymict eucrite sample with a variety of small mafic clasts including extremely fine-grained and glassy clasts. Most pyroxene clasts are pigeonitic with no orthopyroxene noted. An unusual feature of this specimen is the presence of pyroxene clasts with blebby rather than lamellar exsolution. These clasts (En58-62,Wo6) may be similar to pyroxene in Binda and are rare in Elephant Moraine polymict eucrites.
