Abstract
This paper reports the first U-Pb geochronological data on the Precambrian granitoids of the Batomga block (Aldan shield). It was established that the amphibole diorites of this block have an age of 2062 ± 14 Ma, while biotite granites are dated at 2055 ± 7 Ma. These granitoids were subjected to epidote-amphibolie facies metamorphism 1920 ± 8 Ma ago.
