# NASA data for ALH 78127 Weathering: B/C Fracturing: B Fa: 24 mol % Fs: 20 mol % ²⁶Al: 46 ± 3 dpm/kg
Sample is covered with very thin,, shiny fusion crust on the T, B, N and W surfaces. The S surface has remnant patches of fusion crust and the E surface is a fracture surface. The B surface is partially stained by iron oxidation. Where fusion crust is absent, the sample is reddish-brown. Polygonal fractures cover most surfaces. Chipping the sample during processing revealed that nearly the entire sample is severely weathered. One small area of the matrix is not severely weathered and is yellowish gray.
