Abstract
Purpose. To study traces of plastic deformation in quartz of crystalline rocks of the Sea of Azov. Methodology. Work was done in the field to observe the crystallinity of the crystalline rocks of the Sea of Azov. In laboratory conditions, samples were made from samples taken of rocks and quartz, in which traces of plastic deformation were observed qualitatively by visual and optical methods by transmission and reflection. In natural and ultraviolet light, the physical properties of quartz were quantified, and the effects of luminescence in quartz samples and quartz sandstone material were studied and analyzed. Results. The forms of manifestation of quartzity in crystalline rocks of the Azov Sea were studied, geological bodies composed of quartz were tested, samples were taken from samples taken to observe traces of plastic deformation. The fact of luminescence of granular quartz was established, in which traces of plastic deformation act as luminescence centers. The luminescence of Donbass Carboniferous sandstones is shown, in which quartz grains, which bear traces of plastic deformations, serve as luminescence centers. Scientific novelty. A scientific fact has been established that traces of plastic deformation serve as centers of luminescence of quartz. Practical significance. The established effect of the relationship between quartz luminescence and traces of plastic deformation can be used in the field as a diagnostic sign of plastic deformation of quartz and in mine ones for qualitative control of the impact hazard of Donbass sandstones. Keywords: quartz content, granular quartz, luminescence, luminescence center, traces of plastic deformation, impact hazard of sandstones.
