Sturtian glaciation in Siberia: Evidence of glacial origin and U-Pb dating of the diamictites of the Chivida Formation in the north of the Yenisei Ridge
Precambrian Research(2020)
Abstract
•Chivida diamictites are the deposits of an Ice Sheet, covering Siberian craton.•U-Pb dating of zircons yields a Sturtian (~700Ma) age for the Chivida diamictites.•At least two Neoproterozoic glaciation occurred in Siberia.•Sedimentation didn’t cease during Snowball-type Sturtian glaciation.
