| Popis: | The influence of temperature on the development of shock deformation effects in quartz single-crystal targets has been investigated in this parameter study. Quartz targets were pre-cooled to 77 K and shocked parallel to their ( 101 ; − 0 ) orientation in shock reverberation experiments of microsecond shock duration. Shock deformation effects in quartz were characterized by optical and spectroscopic methods. The degree of shock metamorphism in pre-cooled quartz targets has then been compared with literature data from μs-shock reverberation experiments on quartz targets shocked parallel to the same crystallographic orientation but at initial temperatures of 293–903 K. The degree of shock metamorphic overprint in quartz was found to be rather insensitive to temperature variation in the low-temperature region ( |
