# NASA data for ALH 78106 Weathering: A/B Fracturing: A Fa: 24 mol % Fs: 20 mol % ²⁶Al: 44 ± 4 dpm/kg
Ice was noted on the sample when removed from the freezer. This semi-pyramidal shaped specimen appears to be unweathered. It is completely covered with a spotted brown, black, polygonally fractured, ~1 mm thick fusion crust. Shallow regmaglypts are present on all surfaces. A small portion ~2 cm x 1 cm, of fusion crust was broken off the W surface, revealing a nonweathered, light gray matrix with dark and light clasts, as much as 1 mm in diameter. When the meteorite was cleaved in half during processing, abundant unoxidized metal was observed. Light and dark clasts, as much as 2 mm in diameter, were present in the light gray matrix.
