Suevite

Terrestrial breccia composed of angular fragments of different rock types and glass inclusions. Glass can make up more than half of the volume of suevite. Mineral grains in the rock fragments commonly display shock-metamorphic effects. Suevite was named after a rock found at the Ries Crater in southern Germany (photograph).
