High-resolution integrated stratigraphy of the upper Burdigalian-lower Langhian in the Mediterranean: the Langhian historical stratotype and new candidate sections for defining its GSSP [PDF]

open access: yesStratigraphy, 2011
Results of high-resolution integrated stratigraphic studies (calcareous plankton and magnetostratigraphy) of three Mediterranean sections (La Vedova in Central Italy, Contrada Pesciarello in Sicily and St. Peter’s Pool in Malta) and one deep-sea core from the mid-latitude North Atlantic (DSDP Hole 608) are here synthesized. They are compared with those

Lower Bajocian ammonites from the stratotype section of the Etropole Formation kept in the Historical Museum in Etropole (Bulgaria)

open access: yesGeologica Balcanica, 2014
The area of the town of Etropole is famous for the well-preserved Lower Bajocian ammonites, which can be still often found in the nearly located exposures. These ammonites were the source of a number of species that enabled the recognition of the Bajocian in Bulgaria.

The Quaternary of Poland and its stratigraphic classification

open access: yesGeographia Polonica
Quaternary studies in Poland require an improved integration of lithostratigraphy, biostratigraphy, chronostratigraphy, geochronology, magnetostratigraphy, climatostratigraphy and isotope stratigraphy.

Preliminary investigations of an Aptian GSSP candidate at the historical Bedoulian locality near Cassis (Bouches-du-Rhône) and complementary section at the stratotype Barremian locality at Angles (Alpes-de-Haute-Provence)

open access: yesCarnets Geol.
This report presents preliminary investigations of a new candidate for the Aptian Global boundary Stratotype Section and Point (GSSP) at Cassis (Bouches-du-Rhône, France), within the historical Bedoulian stratotype area, and a complementary section at Angles (Alpes-de-Haute-Provence, France). Fieldwork in 2025 identified a promising continuous section (

The Paleocene/Eocene boundary Global Standard Stratotype-section and Point (GSSP): Criteria for Characterisation and Correlation [PDF]

open access: yes, 2002
The choice of a Paleocene/Eocene (P/E) Global Standard Stratotype-section and Point (GSSP) is complicated by the fact that there exists confusion on the exact denotation of the Paleocene and Eocene Series and their constituent lower rank (stage) units ...

Early Aptian δ¹³C and manganese anomalies from the historical Cassis-La Bédoule stratotype sections (S.E. France): relationship with a methane hydrate dissociation event and stratigraphic implications

open access: yesCarnets de Géologie, 2005
Comparison of oxygen and carbon isotope and manganese evolution curves in bulk carbonate from the historical Bedoulian stratotype (Cassis-La Bédoule area, Provence, France) reveals an important geochemical event (negative δ¹³C and high Mn content ...

Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”

open access: yesGeophysical Monograph Series, Page 449-486., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
