Abstract

The paper presents the results of U-Th-Pb (LA-ICP-MS) geochronological studies of detrital zircon from Quaternary sands of the Tokko basin on the eastern flank of the Baikal rift zone. The study shows, that their main sources were Mesoarchean tonalite-trondhjemite orthogneisses and metavolcanics, as well as Meso- and Neoarchean syn- and post-collision granitoids of the Charа-Olekma geoblock of the Aldan shield, which are located near the Tokko basin. Moreover, the supply of sedimentary material into it could have occurred during the melting of glaciers that covered the Udokan Uplift in the south and the Kodar Uplift in the north in the Middle-Late Quaternary.
