Weichselian chronostratigraphy and correlations

Boreas, 1981
The glacial history of the Fennoscandian ice cap beyond some 20,000 years B.P. is fairly poorly known because of the absence of a reliable dating control. The Eemian Interglacial of Europe is not dated at all. The Weichselian Glaciation seems to be characterized by three main glaciation maxima separated by two main interstadial periods (of quite ...

Permian chronostratigraphy in Kansas

Geology, 1990
Correlations between the type Permian System of Russia and North American strata have been difficult for decades because of biostratigraphic and nomenclatural confusion. Consequently, a standard Permian section was established in west Texas that is widely accepted throughout North America. Series of the North American standard section are, in ascending

Unifying Cenozoic chronostratigraphy and geochronology: applying the rules

Newsletters on Stratigraphy
The International Chronostratigraphic Chart (ICC), as the basis of the International Geological Time Scale, is the primary product of the International Commission on Stratigraphy (ICS), itself the principal commission of the International Union of Geological Sciences (IUGS).

Chronostratigraphy of Upper Eocene Microspherules

PALAIOS, 1989
Impact-glass microspherules occur at numerous localities in rocks that can be dated as late Eocene. There is debate as to whether the discovered microspherule layers are the result of two or three impact events. Standard biostratigraphic techniques have been employed to date the microspherule layers.

Chronostratigraphy beyond the GSSP

Stratigraphy, 2007
The introduction of the GSSP concept has been successful to the extent that it has fostered a considerable amount of stratigraphic studies. It has also led to a re-thinking of stratigraphic principles and practices. Chronostratigraphy as practiced today attempts to reconcile two opposite philosophical principles, the rock-time model of Hedberg and the ...

Chronostratigraphy for the World Permian

1978
The marine Permian faunas of the world are subdivided into eight stages and nineteen substages: the Asselian Stage, with the Surenan, Uskalikian, and Kurmaian Substages; the Sakmarian Stage, with the Tastubian, Sterlitamakian, and Aktastinian Substages; the Baigendzinian Stage, with the Sarginian and Krasnoufimian Substages; the Kungurian Stage, with ...

Chronostratigraphie de l'Europe würmienne

Bulletin de l'Association française pour l'étude du quaternaire, 1968
From recent data, the author strives to justify division of the Würm in three parts: Eowürm (75 000 B P. -55 000 B P.), Mesowürm (55 000 B. P. -27 000 B.P.), , Néowürm (27 000 B.P.-10 300 B P.). He tries to caracteris some great natural domains utilizing particularly mousterian and leptolithic settlements maps, « front pioneer » succeeding positions ...

Applications of Probabilistic Biostratigraphy to Chronostratigraphy

The Journal of Geology, 1979
The application of probabilistic methods to biostratigraphy and chronostratigraphy is founded on a well-defined theoretical base with few limitations on the type of events used or their maximum number, potentially allowing for universal application and high resolution.
