Moscow University Geology Bulletin, 2020
The study of the foraminiferal communities from the Paleogene–Neogene reference section at Kvachina Bay in West Kamchatka has made it possible, based on the qualitative composition and the quantitative ratios of the encountered species, to identify 13 layers with foraminifera corresponding to certain intervals of the section and to establish their ...

Carbon isotope stratigraphy and the problem of a pre-Tommotian Stage in Siberia
Geological Magazine, 2001Carbon isotopic oscillations are useful to elucidate the stratigraphy and biogeochemical events around the Precambrian–Cambrian transition. New isotopic data from the Manykaj and Emyaksin formations of the eastern Anabar Uplift (Siberia) help to correlate the Lower Cambrian and Neoproterozoic–Cambrian transitional beds across the Siberian Platform ...

Climate, environment and stratigraphy of the last Pleistocene glacial stage in Poland
Quaternary International, 2016Abstract The aim of the paper is to present general characteristics of the climate in Poland during the Vistulian (Weichselian), expressed by changes of its continentality during warm and cold intervals. This last glacial stage in Poland is commonly subdivided into Early Vistulian (MIS 5d-a), Lower Plenivistulian (MIS 4), Interplenivistulian (MIS 3),

Ordovician series and stages in Chinese stratigraphy: steps toward a global usage
Alcheringa: An Australasian Journal of Palaeontology, 2001The first Chinese Ordovician series was erected by Lee & Chao (1924). Since then, many regional Ordovician series and stage names have been established and mostly published in Chinese. The present study is a review of these regional units with a discussion of their definitions and correlation to the international standard. Among them, the Ichang series,

The stratigraphy of the Callovian and Oxfordian stages (Middle-Upper Jurassic) in northern Scotland [PDF]
Synopsis Outcrops of Middle-Upper Jurassic rocks in northern Scotland are restricted to two sedimentary basins. In the east exposures at Brora (Sutherland) and Balintore (Ross-shire) are part of the Moray Firth basin. In the west major exposures at Staffin and in Strathaird (Isle of Skye) belong to the Minch basin.

New data on ammonites and stratigraphy of the Volgian stage in Spitzbergen
Stratigraphy and Geological Correlation, 2010The stratigraphy of the Volgian in Spitzbergen is refined based on the new fossil collections. The lower Volgian is poorly characterized by ammonites being not subdivided into zones, and the only recognized stratigraphic unit within it are the Beds with Paravirgatites sp. in the upper part of the lower Volgian.

Definition of Late Cretaceous Stage Boundaries in Antarctica Using Strontium Isotope Stratigraphy
The Journal of Geology, 2000Abstract New 87Sr/86Sr analyses of macrofossils from 13 key marker horizons on James Ross and Vega Islands, Antarctica, allow the integration of the Antarctic Late Cretaceous succession into the standard biostratigraphic zonation schemes of the Northern Hemisphere. The 87Sr/86Sr data enable Late Cretaceous stage boundaries to be physically located with

Cambrian stratigraphy and stage subdivision in the Holy Cross Mountains, Poland
Geological Magazine, 1992AbstractThe lithostratigraphic and biostratigraphic subdivisions of the Cambrian sequence in the Holy Cross Mountains of Poland are briefly presented and discussed. In accordance with recent progress in Cambrian stratigraphy and correlation in Great Britain and Scandinavia, a new proposal for chronostratigraphic stages is made.
