# NASA data for ALH 78105 Weathering: B Fracturing: A Pairing: ALH 78103 Fa: 23 mol % Fs: 20 mol % ²⁶Al: 61 ± 7 dpm/kg NTL: 45.3 ± 0.5 krad
The exterior of the sample is irregular and rough on a mm scale. The character of the exterior appears to be the result of the weathering of the fusion crust. Small patches of fusion crust remain on the B and N surfaces. Where the sample is devoid of fusion crust, light to medium gray matrix material with chondrules and lithic clasts is exposed. When the specimen was cleaved the interior of the sample appeared greenish-gray and fine grained. Only a very small amount of a metallic mineral phase is present in the sample. One fracture that penetrates the specimen is stained by iron oxidation along the margins.
