# NASA data for RKP 79001 Weathering: Be Fracturing: C Pairing: RKP 78001 Fa: 23 mol % Fs: 20 mol % ²⁶Al: 58 ± 4 dpm/kg NTL: 6.5 ± 0.1 krad
A small amount of ice was noticed when this meteorite was unpacked. This is not a complete specimen. Thin shiny black fusion crust appears as small patches on each surface. The rest of the surfaces are fractured and rough and yellowish-brown in color. Chondrules can be distinguished, most are small and tan in color but the largest one seen is 6 mm in diameter. Several indentations in the surfaces indicate chondrules may have been plucked out. There is a vein (1-3 mm wide) of dark material on one, surface, probably indicating weathering along a fracture. Fractures are numerous, making the meteorite friable. A small amount of white powder deposit is visible on the fusion crust. The interior matrix is light gray to yellow in color. No metal is visible, oxidation exists as haloes. Gray and cream-colored chondrules ~2 mm in diameter were exposed. RKPA79001 and RKPA79002 may be pieces of a single meteorite.
