Deposits of rock crystal in the Subpolar Urals were discovered in the 1930s, when exploration work for the purpose of finding primary sources was carried out based on finds of surface placers of quartz crystals. Later, the main attention of geologists who studied and explored rock crystal deposits was directed to the study of the conditions of formation and distribution patterns of crystal-bearing bodies. Great progress has been made in solving this problem, and currently a considerable number of indirect indicators have been established that point to the possibility of finding blind pockets of rock crystal in a given area.
