Abstract
We consider high-purity quartzites of the Gargan quartz-bearing zone of East Sayan. The main productive varieties of quartzites have been identified. The structures, textures, chemical composition, and degree of enrichment of the quartzites and the mineral and fluid inclusions in them have been studied. Quartz concentrates of high and ultrahigh purity have been obtained from superquartzite and compact quartzite.
