| Tartalmi kivonat: | Thorough understanding of the shock metamorphic signatures of zircon will provide a basis for the application of this mineral as a powerful tool for the study or recognition of old, deeply eroded, and metamorphically overprinted impact structures and formations. This study of the micro-Raman spectroscopic signatures of naturally shocked (Ries Crater, Germany) zircon crystals and experimentally (38, 40, 60, and 80 GPa) shock-metamorphosed single crystals of zircon contributes to the understanding of the formation of shock-induced microdeformations and phase transformation in zircon under very high, dynamic pressures. The purpose of this investigation is to further investigate the capability of the Raman spectroscopy to document shock deformation and to determine whether specific Raman effects in zircon/scheelitestructure (reidite) can be utilized to determine particular shock pressure stages. |
