# NASA data for ALH 77011 Weathering: C Fracturing: A Pairing: ALH 77011 Fa: 36-4 mol % Fs: 1-33 mol % ²⁶Al: 39 ± 4 dpm/kg
The major portion of the sample is covered with fusion crust. Inclusions are apparent through the thin fusion crust on the B surface. The fusion crust on the T surface is shiny blackish-red and appears to be more severely weathered than the other surfaces. Regmaglypts are present on the E surface. In areas where the fusion crust has been removed, probably by physical processes, many inclusions are apparent in the interior of the stone.
