Abstract

U–Th–Pb geochronological (LA-ICP-MS) stady the detritе zircons from the Late Cainozoic sands of the Olkhon island (the Baikal rift zone) were performed. It is shown that the early Paleozoic magmatic and metamorphic complexes of the Olkhon terrein of the Central Asian Mobile Belt and the Late Carbonian – the Early Permian granitoids of the Angaro-Vitimsky batholith were the main their sources. Transfer of granitoids of the Angaro- Vitimsky batholith were the main their sources. Transfer of the last was carried out on distance not less than 100 km. The assumption is made that it happened by powerful air transfer, and including on ice of Baikal Lake.
