Macroscopic Description - Mitchell Haller
95% of the exterior of this achondrite has jet black fusion crust, glassy and minor rust in areas. The interior matrix is gray with white inclusions, and some minor oxidation.
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer
This meteorite is dominated by coarse-grained basaltic material. Feldspar laths are up to 1.5 mm. Pyroxene grains are also up to 1.5 mm. One finer-grained clast exists, with grain sizes up to 0.5 mm (also pyroxene and feldspar). Mineral compositions are orthopyroxene (Fs59-67Wo3-5), with lamellae of augite (Fs50Wo20, although lamellae were too small to get pure end-member compositions), and plagioclase (An78-85Or0.8-1.7). One olivine analysis was Fa80. The Fe/Mn ratio of the pyroxene is 29-34. The meteorite is a eucrite.
