# NASA data for ALH 85001 Weathering: A/B Fracturing: A/B Fs: 32 mol % ²⁶Al: 110 ± 4* dpm/kg NTL: 0.1 ± 0.01 krad
ALH85001 appears to be an oriented stone covered by a shiny black fusion crust with thick flow lines. Areas devoid of fusion crust have weathered to a brownish-gray color. A discontinuous weathering rind, as thick as 4 mm, was exposed when the stone was chipped. The interior is made up of abundant laths of chalky-looking plagioclase in a light gray matrix. The way this stone has weathered is more typical of the Elephant Moraine eucrites than those found in the Allan Hills.
