Two thin sections were prepared for petrological studies. Full characterization of clasts present is still in progress. The meteorite is partly covered with a brownish fusion crust. On freshly cut surfaces it appears grey to dark grey. Most clasts are subophitic and fine-grained to microporphyritic impact melt breccias, granulitic fragments, intergranularly recrystallized anorthosites, and mineral fragments.
Mafic lithologies are rare.
Melt spherules and impact melt veins are present. The meteorite is crosscut by carbonate veins which are due to terrestrial alteration. Trace elements susceptible to terrestrial alteration are enriched over average lunar highland meteorites concentrations. Ba, As, K, Sr, and Br. Among lunar meteorites DaG 400 is highest in D 18 O, possibly reflecting the presence of terrestrial weathering products.
