Аннотация
A Late Neoproterozoic U–Pb zircon age is established for the first time for arc metadacites (691 ± 8.8 Ma) and basalts (572 ± 6.5 Ma) from the Kiselikha Formation of the Kutukas Series. The manifestation of basaltic volcanism is associated with rifting processes. Our studies specify the Late Precambrian stratigraphy of the Yenisei Range and the evolutionary features of the Sayan–Yenisei accretion belt at the Neoproterozoic stage of its history. The fold-and-thrust structures of the junction zone between the Yenisei Range and the West Siberian Plate may be favorable in terms of the search for unconventional oil and gas traps.
