Early events during the formation of the Ries crater include ejection of moldavite tektites and deposition of the Bunte breccia outside of the uplifted inner crystalline ring of the crater. The restricted location of the moldavites may suggest an oblique impact at the Ries. The Bunte breccia ejecta was emplaced relatively cold and was probably a continuous ejecta blanket. Impact-melt-bearing breccias (suevite) were deposited inside the crater (crater suevite) and deposited on top of the Bunte breccia outside the crater (fallout suevite). The presence of aerodynamically shaped glass bombs in the fallout suevite indicates solidification during high-speed travel through the...
