# NASA data for ALH 78251 Weathering: B Fracturing: A Fa: 23 mol % Fs: 20 mol % ²⁶Al: 56 ± 6 dpm/kg NTL: 49.6 ± 0.5 krad
The exterior of the sample is rough and irregular and macroscopically appears similar to ALH 77105. The sample is completely devoid of fusion crust. A small piece of material has been removed from the S surface, revealing a fine grained, greenish-gray interior. Metallic particles are apparent in the interior of the sample, and some oxidation of these has occurred. Oxidation haloes around metallic particles (1-10%) are also apparent on the sawed surfaces of the sample. Several fractures are apparent with iron oxidation along their margins.
