Results of the U Pb Age of Detrital Zircons from Upper Proterozoic Deposits of the Eastern Slope of the Anabar Uplift
The Upper Proterozoic sequence in the southern part of the East Anabar Basin, as throughout the entire framing of the Anabar uplift, has a two unit terrigenous carbonate structure.

In the north, deposits of the entire sequence are regarded as Early Riphean; in the south, the thickness of these deposits is reduced to 70 m. The overlying stratum is regarded as Upper Riphean–Vendian.
