Macroscopic Description: Roberta Score EET83229 looks similar to other 1983 Elephant Moraine eucrites with the exception of one large brown crystalline clast that has a dimension of 4 x 3 x 1.2 cm.
Thin Section (,5) Description: Jeremy Delaney Typical polymict achondrite breccia with many pyroxene, plagioclase and opaque mineral clasts and a few small lithic clasts. One lithic clast has a feldspar phenocryst, which is an unusual feature for a eucritic clast. Pyroxene clasts have various degrees of exsolution, clouding, and compositional dispersion. Feldspar clasts show variable amounts of shock modification. Many cracks filled with dark weathering products crosscut the thin section. | ||||||||||||||||||||
