Proterozoic Siberia:a promontory of Rodinia
The analysis of Siberian basement geology, Meso- to Neoproterozoic sedimentary successions and magmatism together with recent palaeomagnetic and geochronological data suggest that Siberia could be a promontory of Rodinia. Most of Siberia's margins faced an open ocean in the Meso- and Neoprotero...

The western Siberian passive margin evolved into an active margin in the early Neoproterozoic.
