Le Gargasien de Gargas (Vaucluse, SE de la France) : synthèse des données de terrain et révision de la microfaune de foraminifères et d'ostracodes [The Gargasian of Gargas (Vaucluse, SE France): Synthesis of field data and revision of the foraminiferal and ostracodal microfauna]

Carnets de Géologie, 2009
Because of urbanization the section at Gargas, historical stratotype of the Aptian stage and of the Gargasian substage, is no longer accessible. However, samples taken there in 1966 by one of us make feasible a reinterpretation of this series in the ...

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

Stratigraphy, 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

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

The Depositional Record, Volume 11, Issue 5, Page 1200-1258, November 2025.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

High resolution carbon isotope stratigraphy of the basal Silurian stratotype (Dob's Linn, Scotland) and its global correlation [PDF]

, 1997
Since its designation as the Global Stratotype Section and Point (GSSP) for the base of the Silurian System, the choice of Dob's Linn, Southern Scotland, has received criticism due to the difficulties of relating its well constrained graptolite ...

Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England

Journal of Quaternary Science, Volume 40, Issue 7, Page 1230-1239, October 2025.
ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,

1.38 Ga Four‐Layer Tuff Marker Horizon in North China black Shales as a Chronostratigraphic Boundary for the Pre‐Ediacaran Geological Timescale

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Boundaries in the Phanerozoic chronostratigraphic scale are mainly precisely defined and dated, and many correspond to environmental catastrophes induced by the emplacement of LIPs. The pre‐Ediacaran geological timescale is currently subdivided by approximate absolute ages.

Mining an Anthropocene in Japan: On the making and work of geological imaginaries

Transactions of the Institute of British Geographers, Volume 50, Issue 3, September 2025.
Short Abstract This article addresses how the lithic and the drift might be reworked as an Anthropocene material outside of a chronostratigraphy. Revisiting the finding of a floating fern fossil at the Hashima mine, we delve into a complex array of Geological imaginaries, and undertake our own speculative work.
