EET83232 looks similar to the other 1983 Elephant Moraine eucrites.

Thin Section (,2) Description: Jeremy Delaney

Typical polymict achondrite breccia with a variety of lithic clasts. Pyroxene clasts include pigeonites with micron-scale exsolution lamellae with both clouded and unclouded grains present. Some pyroxene clasts have clear zoning that mimics the irregular clast outlines suggesting that they were metamorphosed after brecciation. Feldspar clasts have shock features and some may be recrystallized. A few feldspar clasts have abundant inclusions of clinopyroxene up to 20 microns in diameter. Mafic clasts vary from coarse to very fine-grained and contain cloudy, exsolved pyroxene. Silica minerals in these clasts appear as both interstitial space filling settings and as coarse lathy crystals that appear to cross-cut the earlier texture. No orthopyroxene was recognized. This specimen is a polymict eucrite similar to EETA79011 and 79004.
