摘要
The U-Pb (ID TIMS) geochronological studies of single zircon grains and their fragments have made it possible to establish that rare-metal alkaline granites of the Katugin massif (2055 +/- 7aEuro'2066 +/- 6 Ma) underwent high-temperature transformations at age levels of 1921 +/- 5 and 1876 +/- 7 Ma.
