# NASA data for ALH 77258 Weathering: B/Ce Fracturing: A/B Fa: 18 mol % Fs: 16 mol % ²⁶Al: 29 ± 2 dpm/kg NTL: 48 ± 1 krad
This is a five sided specimen that is covered with polygonally fractured fusion crust. One small area has been stained by iron oxidation. The sample is ~10.0x9.0x5.0 cm. Sawing the sample in half reveals that the fusion crust is <0.5 mm thick and the sample has no weathering rind. Metallic particles are visible in the yellowish-brown matrix. The matrix material appears to be very porous.
