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 ...

Unresolved issues in Cenozoic chronostratigraphy

Stratigraphy, 2007
Cenozoic chronostratigraphy has been an active area of research over the past 50 years. The expanding search for energy and the development of international scientific drilling have resulted in a wealth of stratigraphic data. Many issues in Cenozoic chronostratigraphy, however, remain unresolved.

A conodont-based Silurian chronostratigraphy

Geological Society of America Bulletin, 1989
Ranges of 79 conodont species are used to effect a graphic correlation of upper Llandoverian-Pridolian (Silurian) rocks in 30 stratigraphic sections in Europe and North America. A Silurian Composite Standard Section (CSS) developed by this method provides the total stratigraphic ranges for all species for which there is information in the system. These

Updated Quaternary Chronostratigraphy

2014
With new developing, the span of Quaternary was defined as 1.8 Ma at the 27nd International Geological Congress held on 1984 in Moscow. In spite of discussion on Pliocene-Pleistocene boundary and span of Quaternary, this defining has been accepted in general. One of the hot topics discussed at the 32nd International Geological Congress held in Florence

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 ...
