# NASA data for ALH 77274 Weathering: C Fracturing: A Fa: 18 mol % Fs: 16 mol % ²⁶Al: 53 ± 2 dpm/kg
A small patch of dull black fusion crust remains on the B surface. The remaining surfaces are devoid of fusion crust and are weathered and stained reddish-brown by iron oxidation. One small fracture is present on the B surface. After sawing the interior of the sample revealed small metallic flecks, probably due to the abrasion of the saw blade against the metal included in the meteorite, as the remainder of the stone's sawed surface appeared a reddish-brown.
