Hofmann) The sample consist mainly of olivine and pigeonite and shows the characteristic ureilitic texture, typical grain size is 0.8-2.0 mm. Olivine has reduced rims (width 50-100 μm) with minute Fe metal inclusions, partly oxidized due to weathering. Carbon platelets (up to 2 mm in length) consist dominantly of diamond. Silicates are weakly shocked (S2). Medium weathering, most iron metal oxidized while silicates are not affected. Geochemistry: (T.
