Andreas writes:
This full slice from a Boxhole individual shows a remarkable reheated rim (Alpha-2-Zone). The Widmannstätten pattern recrystallized due hot temperatures during the flight through the atmosphere of Earth. Recrystallization happens at temperatures over 750°C. Usually a reheated rim on a fresh individual of an iron meteorite is 1-2 mm thick. In this case, the rim measures 6mm at its widest!
