Northwest Africa 669 (NWA 669)

Petrography: Chondrules are recrystallized and poorly defined. A few plagioclase grains reach 100 µm in diameter. Olivine has undulose extinction. Silicate-rich shock veins (~50 μm × 6 mm) including small metal blebs cut across the meteorite. Also present are small metal and sulfide veins. Some coarse metal grains are elongated. The sample was probably shocked and annealed.
