Abstract
The results of U–Th–Pb (LA–ICP–MS) geochronological studies of detrital zircon from the Quaternary sands of the Tokko Basin on the eastern flank of the Baikal Rift Zone are reported. It is shown 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 input of sedimentary material into the basin could have occurred during the melting of glaciers that covered the Udokan Ridge to the south and the Kodar Ridge to the north in the Middle–Upper Quaternary.
期刊介绍：
Doklady Earth Sciences is a journal that publishes new research in Earth science of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
