# NASA data for ALH 78050 Weathering: B Fracturing: B Fa: 23 mol % Fs: 20 mol % ²⁶Al: 44 ± 3 dpm/kg
This is not a complete specimen. The N, T and B surfaces are fracture surfaces that are stained reddish-brown by iron-oxidation. Inclusions in. the meteorite are apparent on these surfaces and patches of remnant fusion crust remain on the B surface. The fusion crust, where present, is mottled brown and black. Unoxidized (<5%) metallic particles, and some metallic particles with oxidation halos are apparent on the sawed surfaces of the sample. Fracturing, with oxidation staining along the margins, is apparent on the W sawed face, as are small irregular inclusions.
