摘要：

Fracture mechanism and dynamics is studied with a time resolution of 2 ns in the quartz, granite, gabbro-diabase, and calcite samples in a shock wave field. It is found out that jets of positively charged ions are ejected from the shock-loaded surface of minerals. The structure of the surface layer of these rocks after loading by shock waves is studied by the infrared, Raman, and photoluminescent spectroscopy. It is established that in the surface layers of quartz and granites, diaplectic glasses are formed, whereas in the surface layers of calcite-the high pressure phase-calcite III is produced.
