In search of the Global Stratotype Sections and Points (GSSPs) of the Burdigalian and Langhian Stages and paleoceanographic implications

Università degli Studi di Parma
Abstract
This project intends to search sequences having suitable requirements to be proposed as candidate for the definition of the Global Stratotype Sections and Points (GSSPs) of the Burdigalian and Langhian Stages in agreement with the perspectives of the Subcommission of Neogene Stratigraphy (SNS). The most urgent and pressing work is, therefore, to find and study sections showing as better as possible the requested features. The research program is focused on the high-resolution biostratigraphy, based on calcareous plankton (foraminifera and nannofossils), of the late Aquitanian to early Langhian stratigraphic interval. At present, the Burdigalian and its boundary with the underlying Aquitanian are not yet defined either from a biostratigraphic, magnetostratigraphic and cyclostratigraphic point of view. The Langhian, which has been studied in a previous COFIN project (principal investigator: Prof. R. Sprovieri) from some of the participants to the present research, must be re-examined for its lower part because the lower boundary (as historically defined) was not identified with enough detail in the investigated sections.
The analysis of the calcareous plankton, the paleomagnetism, and the sedimentary cyclicity will be the tools applied to achieve the objective of the project. Moreover, through the study of the benthic foraminifera and the stable isotope geochemistry (oxygen and carbon) the main paleoenvironmental and paleoceanographic features characterizing the late >>>

Research Objectives
The aim of the this project is to identify sections that can be considered as candidates for the definition of the Global Stratotype Sections and Points (GSSPs) of the Langhian and Burdigalian Stages.This objective will be achieved through integrated stratigraphy (high-resolution calcareous plankton biostratigraphy, magnetostratigraphy and cyclostratigraphy) studies of the upper Aquitanian to lower Langhian stratigraphic interval. A high-resolution biostratigraphic record for this interval might contribute to achieve the objectives of the Subcommission of Neogene Stratigraphy (SNS) of the International Commission on Stratigraphy (ICS) for the next few years, i.e the definition of the GSSPs of the remaining Neogene stages (Langhian and Burdigalian stages) not yet formalised. A detailed and accurate integrated (planktonic foraminifera and calcareous nannofossils) biostratigraphic record was, in fact, of great relevance in the definition of the GSSPs of the Neogene stages, revealing secondary bioevents which remarkably increase the biostratigraphic resolution of the existing zonal schemes.
To achieve the aim of the present project is fundamental:
1) to identify deep marine successions which encompass the Aquitanian/Burdigalian and Burdigalian /Langhian boundaries, both in the Mediterranean and open ocean areas;
2) to improve the resolution of the existing biostratigraphic schemes through high-resolution quantitative studies of planktonic foraminifera and >>>

National and international background
During the last twenty years, the Subcommision on Neogene Stratigraphy (SNS) (to which some of the participants to the present project are involved) made a great effort in providing clarity and stability in the Neogene Chronostratigraphic Scale by selecting and defining Global Stratotype Sections and Points (GSSPs) for Series and Stages. Up to now the GSSPs of the base of the Pleistocene series (Aguirre and Pasini, 1985), of the Gelasian (Rio et al., 1998), Piacenzian (Castradori et al., 1998), Zanclean (base of the Pliocene series, Van Couvering et al., 2000), Messinian (Hilgen et al., 2000a), and Tortonian stages (Hilgen et al., 2005), and of the Neogene System (Steininger et al., 1997) have been ratified by the International Union of Geological Sciences (IUGS). At the moment a proposal for defining the GSSP of the Serravallian stage is in preparation (Hilgen et al., in press.). These results were obtained by the remarkable progress recently made in high-resolution integrated stratigraphy studies (cyclostratigraphy, magnetostratigraphy, calcareous plankton biostratigraphy, stable isotope stratigraphy and radiometric dating) mainly by several Italian and Dutch researchers. These studies allowed the establishment of an astronomically tuned stratigraphic framework both in the Mediterranean and the open ocean (e.g., for the Miocene, Shackleton and Crowhurst, 1997; Hilgen et al., 2000b, 2003; Caruso et al., 2002; Lirer et al., 2002; Sprovieri et al., 2002; Holburn et al., 2005 >>>
