Title: U-Pb (LA-ICP-MS) dating of detrital zircons from clastic sediments of upper part of Precambrian basement of Northern Timan
Abstract: The article presents the first U–Pb data on the age of detrital zircons from clastic sediments of Yambozero Formation (Barmin Group) which constitutes the upper part of the Precambrian sequence of the Northern Timan. Age data for 80 zircon grains (LA-ICP-MS) cover the range of 989–2713 Ma. Weighted average age of the three youngest zircons yields the age of 1004±15 Ma which provides grounds to assume that sediment deposition took place in late Riphean (Neoproterozoic). The accumulation of clastic sediments of Yambozero Formation was controlled mostly with terrigenous material from eroded rock complexes coeval with crystalline complexes of Fennoscandia and Central Russian Belt.
