Rare-metal metasomatitesShpolyansko-Tashlitskiy ore region are presented areal (greisenizated rocks) and exocontact (recrystallizated gneisses; apoamphibolitebiotitites and apohyperbasitephlogopitites) types. Ironmagnesian micas of biotitites and phlogopitites (cesium-rubidic biotite and rubidium-cesium phlogopite) can have commercial significance at extraction of the main component. In addition, apohyperbasitephlogopitites can be accompanied beryllium mineralization, including an emerald mineralization.
