# NASA data for RKP 78002 Weathering: Be Fracturing: A/B Fa: 18 mol % Fs: 15 mol % ²⁶Al: 49 ± 3 dpm/kg
This tabular shaped meteorite has 4 flat and 2 semi-rounded surfaces with sharp ridges. 0.5 mm thick black, polygonally fractured fusion crust covers the entire specimen except for areas along the ridges where it has been broken off. The areas void of fusion crust are greenish-brown in color and contain numerous inclusions. One fracture penetrates the interior of the meteorite. After drying for several days in the nitrogen cabinet, minute amounts of white deposit appeared along the polygonal fractures. The cut face reveals a weathering rind ~1-4 mm thick. Abundant metal blebs are obvious with most of the metal having oxidation halos around them. Several chondrules (~2 mm diameter) are present.
