Macroscopic Description - Kathleen McBride
These achondrites are covered with brown/black fusion crust (50-85%), shiny in areas and have some areas with polygonal fractures. The interior matrices are tan with small mm sized white, tan and black inclusions. 0221 has dendritic looking dark veins that surround some clasts.
Thin Section (,2) Description - Cari Corrigan, Linda Welzenbach, Andrew Beck and Nicole Lunning
These meteorites are similar enough that one description is sufficient. Thin sections of each show a groundmass of coarse (up to 1.5 mm) comminuted pyroxene, with minor plagioclase and SiO2. Orthopyroxene has a composition of Fs32-36Wo2-4, augites are Fs12-15Wo40-43 and plagioclase is An84-89Or0-1. The Fe/Mn ratio of the pyroxene is 26-30. These meteorites are diogenites.
