The problems of stratigraphy on devon оf Polar Urals and Pay-Hoi
- Authors:
- A. L. Zherlygin
The legends of the Polar Urals and Pay-Hoi map series were estimated for proving the mapped subdivisions due to geological survey in the scale 1:200000 conducted in Kara-Silovskaya area (on western slope of the Arctic Urals and the range Pay-Hoi). In the result it was found out that Eletskaya Structure-Formation Zone in Devon was divided into a great number of stratigraphic units, reflecting the lateral substance changes of the same age level. According to it all units are conventionally valid and there are same equal ones among them. The biohermal massifs are not distinguished as independent units.

A new regional stratigraphical scheme of the upper palaeozoic of Taimir
- Authors:
- S. B. Shishlov
The structural-genetic analysis of the Upper Palaeozoic sections of Taimir allowed us to distinguish seven geoformations – regional geological bodies, which had been formed as a result of transgression-regression cycles in the palaeobasin. The geoformations are considered as the regional stratigraphic units (Horizont in Russian usage). Lithologically uniform parts of the geoformations (gradations), which resulted from lateral differentiation of landscapes during the regional sedimentation cycle, are used as local stratigraphical units. The developed stratigraphical scheme based on the geoformations and gradations is the geohistorical model of the Late Palaeozoic of Taimir.
