The results of U–Pb-isotopic dating of detrital zircons from sandstones of the Proterozoic Pogor'uy Fm. from the northern and southern parts of the Eastern-Angara block of the Yenisei Ridge are presented. The sandstones of the northern part of the Eastern-Angara block are dominated by the Archean and Paleoproterozoic populations of detrital zircons, while in the samples from the southern part of the Eastern-Angara block up to 25% of the Mesoproterozoic age grains have been fixed. The dates of

... trital zircons allow us to constrain the maximum sedimentary age of the Pogor'uy Fm. and the entire interval of its formation as 1.2–0.9 Ga. The paleogeographic features of the formation of the Pogor'uy Fm. in the context of existing views on a location of Siberia within the Rodinia supercontinent are considered.
