THE STRATIGRAPHY OF THE UPPER BATHONIAN TO MIDDLE OXFORDIAN SUCESSION OF THE ARAGONESE BRANCH OF THE CORDILLERA IBÉRICA (SPAIN) AND ITS EUROPEAN CONTEXT

Rivista Italiana di Paleontologia e Stratigrafia, 2004
The Upper Bathonian-Middle Oxfordian succession of the Aragonese branch of the Cordillera Ibérica is one of the most completely developed in Europe and includes localities of international importance for Jurassic bio- and chronostratigraphy.

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.

Traces de volcanisme explosif dans le Campanien pyrénéen aux alentours du stratotype de limite Campanien-Maastrichtien à Tercis (SO France, N Espagne). Repérage biostratigraphique avec une étude particulière du foraminifère Radotruncana calcarata [Traces of explosive volcanism in the Pyrenean Campanian around the Campanian-Maastrichtian boundary type section at Tercis (SW France, N Spain). Biostratigraphy with emphasis on the foraminifer Radotruncana calcarata]

Carnets de Géologie, 2010
Pyroclastic material including idiomorphic crystals of sanidine, biotite, and apatite, first identified in the type section at Tercis are contemporaneous with the Radotruncana calcarata (planktonic foraminifer) total range zone.

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

Carnets 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 ...

THE GELASIAN STAGE: A PROPOSAL OF A NEW CHRONOSTRATIGRAPHIC UNIT OF THE PLIOCENE SERIES

Rivista Italiana di Paleontologia e Stratigrafia, 2017
A new Stage, the Gelasian, is proposed as the third upper subdivision of the Pliocene Series. The GSSP of the base of the Gelasian Stage and of the Middle Pliocene-Upper Pliocene boundary is coincident with a "sapropel" level which outcrops in the Monte ...

The Deshayesitidae Stoyanov, 1949 (Ammonoidea) of the Aptian historical stratotype region at Cassis-La Bédoule (SE France)

Carnets de Géologie, 2006
One of the significant results of the multidisciplinary investigations carried out during recent years in the Lower Aptian historical stratotype of the Cassis-La Bédoule region (South-Eastern France) was a proposal to update the local Upper Barremian ...
