# NASA data for MET 78002 Weathering: B Fracturing: A Fa: 23 mol % Fs: 20 mol % ²⁶Al: 47 ± 3 dpm/kg
Thin dull black fusion crust is present on three surfaces of this pyramidal specimen. The fusion crust is pitted, apparently due to the preferential weathering of small inclusions. The T, W and B are fracture surfaces that are stained reddish-brown. Many clasts, as much as 3 mm in diameter, can be seen on the T and W surfaces. Chipping for a suitable thin section sample revealed a greenish-gray matrix which contained metallic particles, some of which have iron oxidation halos.
