The Kerpylian was preceded by an accretion to the Siberian craton of its surrounding microcontinents while...

... and considerable gaps in sedimentation. These events are well-expressed where they occurred under intense contraction or, on the contrary, are veiled where extension was predominant. The boundary between the Kerpylian and Lakhandinian, subdivisions of the Mayanian, is not bearing on important events and is hardly...

... with the aforementioned events. The hypothesis on intensive events separating the deposition of the Bol’shoi Pit Group of the Kerpylian Horizon and the Tungusik Group of the Lakhandinian Horizon is not supported by the new data. The change from carbonate facies into siliciclastics in the west was misinterpreted...

... subdivisions of the Siberian Neoproterozoic such as Mayan (Kerpylian + Lakhandinian), Baikalian, Yudomian, or Vendian bear on principal tectonic rearrangements. These units are separated from the underlying formations by the event boundary having something in common with the late Grenville Orogeny...

... is now considered independent (see below). The most complete and well-studied Late Precambrian section of the Yenisei Ridge is localized in the Teya trough. Two pre-Baikalian units of the Upper Riphean (Kerpylian and Lakhandinian) correspond there to the closely related Bol’shoi Pit and Tungusik...

The most significant borders of tectonic restructurings are documented at 1600, 1350, 1100, 850, and 650 Ma; they coincide with the lower boundaries of the Siberian scale of the Upper Precambrian: Uchurian, Aimchanian, Mayaian (Kerpylian + Lakhandinian), Baikalian...
