# NASA data for RKP 79004 Weathering: B/C Fracturing: B Fa: 18 mol % Fs: 16 mol % ²⁶Al: 45 ± 3 dpm/kg
When the Reckling Peak pebbles were brought out to be initially processed, it was found that six stones appeared identical. Field Notes state that they were found close to each other. Therefore they have been renumbered as one specimen. All six stones have the same black-brown fusion crust on at least one surface. No stone was totally covered with fusion crust, but two stones have fusion crust on a fracture surface indicating the meteorite broke up in the atmosphere upon entry. The fracture surfaces have all weathered to a reddish-brown color and have a uniform pitted surface where chondrules and clasts have been plucked away. Numerous chondrules are obvious from 3 mm to <1 mm in diameter. The interiors of the pebbles are mostly weathered with some gray colored material existing.
