Northern Adriatic Runoff During Pliocene Sapropel Deposition: Implications for Mediterranean Deoxygenation

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract The Piacenzian (Pliocene) warm period featured extreme low‐oxygen conditions and organic‐rich (sapropel) sedimentation in the Mediterranean Sea, yet the processes operating along northern borderlands and marginal basins remain poorly constrained.

Biostratigraphy of Gurpi Formation in Samand anticline (Lurestan province) Based on calcareous nannofossils [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2017
The present study is an attempt to biostratigraphically classify the rocks of Gurpi Formation at Samand Anticline with the help of calcareous nannofossils. The succession measures 197 meters in thickness and consists of shale, marl and marly limestone. A

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

open access: yesPaleoceanography 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

open access: yesBasin 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.

Fluid Pathways and Sources Driving Recurring Pockmark Formation on the Chatham Rise, New Zealand

open access: yesBasin Research, Volume 38, Issue 5, September‐October 2026.
Quasi‐3D seismic data interpretation and spatial pattern analysis indicate that pockmark formation on the SW Chatham Rise is likely driven by a combination of compaction‐related dewatering during polygonal faulting and silica diagenesis, coupled with deeply‐sourced, possibly CO2‐rich fluids from subducted limestones migrating along prominent basement ...

Integrated stratigraphy of the Upper Barremian–Aptian sediments from the south-eastern Crimea

open access: yesGeologica Carpathica, 2018
Previous studies made in different parts of the world have shown that Barremian–Aptian times imply many difficulties in deciphering the biostratigraphy, microfossil evolution and correlation of bioevents.
