Chapter A5 Langhian, serravallian, and tortonian historical stratotypes
1995Publisher Summary This chapter discusses Langhian, Serravallian, and Tortonian historical stratotypes. Chronostratigraphy does represent a basic common language of communication in Earth Sciences. However, most chronostratigraphic units of the standard Geologic Time Scale lack an appropriate and rigid definition in the rock stratigraphic record ...

Comptes Rendus de l'Académie des Sciences - Series IIA - Earth and Planetary Science, 1998
A high resolution carbonate carbon-isotope stratigraphy is established on bulk carbonates from the type locality of the Lower Aptian (= Bedoulian). This exceptionally expanded series permitted us to recognize two marked positive [delta]13C excursions. Correlation with the biostratigraphic data shows that the first excursion commences immediately after ...

Introduction to Part A Chronostratigraphic units: Historical stratotypes and global stratotypes
1995Publisher Summary This chapter discusses historical and global stratotypes. In agreement with common usage, the word “stage” is used in this presentation; both for the actual rocks deposited during an interval of time, and for the interval of time itself (sometimes called “age”).

Chapter A1 The aquitanian historical stratotype
1995Publisher Summary The Aquitanian fossiliferous marine deposits underlie a dark grey limestone with Planorbis and Limnaea. This unit is considered to be the top of the Aquitanian in this area. A level with Pecten beudanti is found above it, and contains a new fauna characteristic of the Burdigalian.

Marly limestones from La Bedoule (Bouches-du-Rhone, SE France), historical type-locality of the lower Aptian, contain in their lowermost part a rich ammonite fauna belonging to the heteromorphic genus Pseudocrioceras. Up to the present this level, corresponding to the Pseudocrioceras coquandi Zone of Busnardo (1984), was considered by ammonitologists ...

Chapter E2 The historical stratotype of the Maastrichtian: A review
2001Sommaire La stratigraphie des couches du Campanien superieur et du Maastrichtien dans la region type (etendue) de l'Etage Maastrichtien (SE Pays-Bas, NE Belgique) est examinee. La subdivision lithostratigraphique fine de ces couches n'est toujours pas accompagnee d'une biozonation aussi detaillee tandis qu'il existe d'importantes lacunes ...
