Chapter A8 The messinian historical stratotype and the tortonian/messinian boundary

Developments in Palaeontology and Stratigraphy, 1995
Publisher Summary This chapter discusses the Messinian historical stratotype and the Tortonian/Messinian boundary. The Messinian sediments in the Pasquasia-Capodarso section have a thickness of about 180 m. In 1960, the section was well exposed, continuously so from the Tortonian (outcropping for about 130 m) to the lower Pliocene (outcropping for ...

Chapter A1 The aquitanian historical stratotype [PDF]

open access: yes, 1995
Publisher 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.

Chapter A7 Planktonic foraminiferal biostratigraphy of the tortonian historical stratotype, rio mazzapiedi-castellania section, northwestern Italy

Developments in Palaeontology and Stratigraphy, 1995
Publisher Summary This chapter discusses the planktonic foraminiferal biostratigraphy of the Tortonian historical stratotype, rio mazzapiedicastellania section, northwestern Italy. The biostratigraphic interpretation of the Rio Mazzapiedi-Castellania section presented in this work differs from that of Cita and Blow (1969) mainly in the evaluation of ...

Correlation of biostratigraphic and stable isotope events in the Aptian historical stratotype of La Bédoule (southeast France)

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 ...

The ‘Pseudocrioceras beds’ at La Bédoule (SE France) and the position of the Barremian-Aptian boundary in the historical lower Aptian stratotype

Comptes Rendus de l'Académie des Sciences - Series IIA - Earth and Planetary Science, 1997
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 A5 Langhian, serravallian, and tortonian historical stratotypes

1995
Publisher 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 ...
