Nördlinger Ries Impact Crater

The Nördlinger Ries is a 24 km-diameter impact crater formed 14.808 ± 0.038 million years ago, identified by coesite in suevite and characterized as a rare Earth rampart crater with fluidized ejecta. A nearby 3.8 km Steinheim crater likely formed 0.5 million years later, and the impact generated ~72,000 tonnes of microscopic diamonds and moldavite tektites dispersed up to 450 km.
