# NASA data for ALH 77226 Weathering: Ce Fracturing: C Pairing: ALH 77004 Fa: 18 mol % Fs: 16 mol % ²⁶Al: 59 ± 3 dpm/kg
A small patch of dull black fusion crust was present on the S surface of the sample. The W surface of the specimen was concave and flow bands were present in the T-B direction. The specimen is severely fractured and during processing crumbled into many pieces. Nearly all the material exposed during processing was extensively stained by iron-oxidation. However, a few small areas on the exposed material are not as severely stained by iron oxidation and appear light gray.
