Riesite, a New High Pressure Polymorph of TiO<sub>2</sub> from the Ries Impact Structure

This paper describes riesite, a new high-pressure polymorph of TiO<sub>2</sub> from the Ries impact structure, Germany. Riesite occurs in shock-induced melt veins within xenoliths of bedrock in suevite. It is structurally closely related to srilankite from which it differs by having two...
