Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Developing a new species-level database of Cretaceous calcareous nannoplankton occurrences – Uneptune [PDF]

Journal of Micropalaeontology
Calcareous nannofossils are abundant and globally distributed fossils that are widely used in the study of stratigraphy and palaeoclimate. A large number of nannofossil data have been generated over the past several decades, but the information is ...

THE MIDDLE EOCENE IN THE ALPINE RETROFORELAND BASIN (NORTHERN ITALY): SEDIMENTARY RECORD OF A “MESO-ALPINE” ARC-TRENCH SYSTEM IN THE ALPS

Rivista Italiana di Paleontologia e Stratigrafia, 2023
The middle Eocene Cibrone Formation of Brianza (central-western Lombardy) represents an important stratigraphic record to understand a key step of the tectonic evolution of the Alpine range poorly recorded elsewhere.

Orbital Control of Reticulofenestra (Calcareous Nannofossils) Assemblages During the Early Pliocene

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Orbital changes have shaped Earth's climate system and influenced the evolution and spatial distribution of marine plankton, including coccolithophores. Some studies have assessed eccentricity's impact on the diversity and morphological evolution of Noelaerhabdaceae taxa during the Quaternary.

Learning From Crushing Failures: Changes in Physical Properties Reveal the Mechanics of Submarine Carbonate Landslides

Basin Research, Volume 38, Issue 5, September‐October 2026.
Changes in the physical properties of calcareous ooze between intact weak layers and glide planes within the same stratigraphy provide new constraints on the deformation processes and mechanical factors that control the mobility and erosive behaviour of submarine carbonate landslides.

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, Volume 73, Issue 5, Page 1631-1663, August 2026.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.
