# NASA data for LAP 03781 Weathering: B Fracturing: A/B Pairing: LAP 91900 Fa: 22 mol % Fs: 23 mol %
The exterior of these diogenites has chocolate brown patches of fusion crust. The exposed interior has a rough texture and light green to white clasts. The interior is a light matrix, stained in areas with a washed out rusty color. Green clasts ranging in size from < 2 mm are visible.
The sections show a groundmass of coarse (up to 1.5 mm) comminuted pyroxene of composition of Fs₂₃Wo₂. The meteorites are diogenites and are compositionally similar to LAP 91900, with which they may be paired.
