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)

open access: yesSedimentology, 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 ...

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Disentangling the Regional and Contextual Dependencies of Climate Effects on Global Maize Yield

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Maize is a cornerstone of global food security, yet the effects of interannual climate variability on its yield under varying production contexts remain not fully understood. Using Köppen climate zones, we coupled random forests with Shapley additive explanations to disentangle water‐heat drivers from three perspectives: yield state, cropping ...

Camp Creek Revisited, One More Time: Evaluating Multiple Approaches to Quantify Peak Flow Response to Forestry for a Medium‐Size Snow‐Dominated Catchment

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Forest disturbance effects on peak flows have been debated for decades. Paired‐catchment analysis (PCA) has been criticized in relation to the long‐term stability of pre‐harvest regressions and the inability of chronological pairing to characterize changes in event frequency.

Problems in the identity of "Crioceras" barremense Kilian, 1895 (Ancyloceratida, Late Barremian), and their proposed resolution

open access: yesCarnets de Géologie, 2010
The study of "Crioceras" barremense Kilian was undertaken as a part of the revision of the Hemihoplitidae. This species was considered "classic" and has been used as the index of an Upper Barremian subzone; this usage raises a number of problems.

MIDDLE EOCENE TO EARLY MIOCENE FORAMINIFERAL BIOSTRATIGRAPHY IN THE EPILIGURIAN SUCCESSION (NORTHERN APENNINES, ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2001
A quantitative biostratigraphical study was performed on the foraminiferal assemblages from 15 stratigraphic sections of the Epiligurian Succession (Middle Eocene-Early Miocene, Northern Apennines, Italy).

Provenance Constraints on Early India–Asia Collision: Evidence From the Late Cretaceous–Early Cenozoic Sulaiman–Katawaz Basin Fill

open access: yesBasin Research, Volume 38, Issue 5, September‐October 2026.
Integrated detrital zircon U–Pb, Nd–Sr isotopes and thermochronology record western Indian‐margin provenance reorganisation. Late Cretaceous–Palaeocene sediment supply was Indian‐affinity; Asian‐affinity input appeared across the Palaeocene–Eocene transition (~56.5–54.7 Ma), suggesting India–Asia collision was underway, while mixed provenance persisted

Ammonite biostratigraphy of the Aalenian and Lower Bajocian (Middle Jurassic) near Böttstein (Canton Aargau, Northern Switzerland) [PDF]

open access: yesZitteliana
A stratigraphic section exposing strata from the upper boundary of the Opalinus Clay to the middle of the Passwang Formation (Middle Jurassic) is described from the abandoned Schmidberg clay pit near Böttstein in the Aare Valley (Aargau, Jura, northern ...
