A brief summary of the geological characteristics of rare-metal pegmatites of the Eastern Sayan is given. According to muscovite their age was determined by the potassium-argon method to be 1700 to 1800 miilion years; according to microcline, 1300 million years. On connection with the incomplete preservation state of radiogenous argon in the microcline, the age of the rare- metal pegmatites of the Eastern Sayan is adopted as 1700 to 1800 million years (data according to muscovite).
