A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Zaplavnensky horizon - a new stratone in the Lower Triassic of the East European platform

Известия высших учебных заведений: Геология и разведка, 2016
A new horizon, called Zaplavnensky, is suggested on the base of verhnesukhorechenskaya subsuite of Buzulukskaya depression in the Lower Triassic of the East European platform.

CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY AND PALEOCEANOGRAPHY OF THE TOARCIAN OCEANIC ANOXIC EVENT AT COLLE DI SOGNO (SOUTHERN ALPS, NORTHERN ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2015
We present calcareous nannofossil biostratigraphy and abundances for the Upper Pliensbachian-Lower Toarcian interval, including the Toarcian Oceanic Anoxic Event (T-OAE), represented by the Fish Level at Colle di Sogno (N Italy).

New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

Oligocene deep-water agglutinated foraminifers at Site 985, Norwegian Basin, southern Norwegian Sea [PDF]

, 1999
The stratigraphic distribution of deep-water agglutinated foraminifers was examined using 50 samples from Ocean Drilling Program (ODP) Hole 985A, drilled on the gentle slope of the Iceland Plateau in the Norwegian Basin. A total of 40 species and generic

Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...

The Late Pliocene–Middle Pleistocene Large Mammal Faunal Units of Greece

Quaternary
Located at the eastern corner of Mediterranean Europe, Greece occupies a critical position for mammal dispersals to/from Europe, Asia, and Africa and constitutes a potential passageway towards Western Europe.

Toward a Robust Plio‐Pleistocene Chronostratigraphy for ODP Site 762

Geophysical Research Letters, 2020
The advent of rapidly acquired proxy records provides paleoceanographers and paleoclimatologists with a wealth of high‐resolution data. These data are a boon for the community, as they enable millennial or even submillennial scale interpretation of past ...
