The possibility of detecting crystal-controlling structures using the method of studying induced thermoluminescence of quartzites sampled from the surface or from drill hole cores was analyzed.
The practical value of rock crystal deposits is largely determined by the quality of crystals, which depends to a large extent on the development of various kinds of defects in them. Analysis of the quality of raw materials is necessary at all stages of industrial development of deposits: from prospecting to exploitation and exploration ...
Physicochemical conditions of mineral formation in natural conditions rarely remain constant, experiencing gradual or pulsagaon changes, which is reflected in the zonal and vectorial structure of individuals ...
Examining quartz crystals from western North Carolina, A. Gill noted differences in a number of sharp rhombohedra under the faces of the positive {1011} and negative {0111} rhombohedra.
