The meteorite consists of a coarse- and a fine-grained lithology both predominantly composed of anorthosite clasts , olivine aggregates and subordinate Ca-rich pyroxene grains set in abundant plagioclase-rich melt rock matrix. Anorthosite is partly transformend into maskelynite. While parts of the melt are glassy showing some flow textures, other regions are recrystallized to small often lath-shaped plagioclase crystals. Olivine aggregates are mostly composed of numerous subgrains with slightly variable composition. Ca-pyroxene appears to be more common in the coarse-grained lithology. Minor phases include chromite, ilmenite, and kamacite.
