...V.V. Khomentovsky; K.E. Nagovitsin; A.A. Postnikov Abstract The Mayanian (1100–850 Ma) is an all-Siberian stratigraphic subdivision of the Neoproterozoic distinguished on the basis of generalized geological and paleontological data for the Maya Group in the southeast of the Siberian craton...

... of these structures can be, in turn, divided into several structure-facies zones. As in the south, three main stages of development have been established in the Neoproterozoic of the above structural elements, which correspond to the Mayanian, Baikalian, and Vendian. The most considerable modifications are made...

... been established for all these structures, but the location and nature of boundaries between them as well as their age are still debatable. The information available casts doubt upon many universally accepted concepts. It is proven that the Maya Group giving rise to the Mayanian, the lower...

... here the Mayanian. The fundamentally different nature of the events associated with the next, Baikalian stage of the development allows its tripartite subdivision in the region. Deposition of the Lower Baikalian (the Oslyanka Group) was preceded by the crustal extension at the junction between...

... were used to argument for his principal statements: “The age of the oceanic volcanosedimentary and volcanogenic deposits in the Chukchi-Borzov and Zhdanov structure-facies zones is essentially refined. It is proven (stressed by me — V.V.) that they correspond to the Mayanian alone” (p. 862). “Vast...

... Groups. The Kirgitei Subgroup with distinct age boundaries is distinguished in the upper Tungusik Group ( Khomentovsky, 2007 ). The Kerpylian and Lakhandinian Horizons are combined into the Mayanian, which is an all-Siberian stratigraphic subdivision ( Khomentovsky, 1996 ; Khomentovsky et al., 2008...

... succession of the Siberian platform was early on subdivided into a series of Regional Stratigraphic units considered as the types for potentially global biostratigraphic subdivisions of the later Proterozoic Eon: the Uiaian, Aimchanian, Mayanian (Kerpylian and Lakhandinian), and Baikalian ( Khomentovsky et...
