Industrial Gamma Radiation Signals: An Untapped Resource to Reconstruct Neogene Paleoclimate Off Northwest Australia

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Paleoceanographic reconstructions require both high‐resolution temporal records and high‐density spatial coverage. Scientific drilling provides detailed paleoclimate time‐series, but its spatial distribution limits our ability to capture regional climate dynamics.

AN INTEGRATED CALCAREOUS PLANKTON BIOSTRATIGRAPHIC SCHEME AND BIOCHRONOLOGY FOR THE MEDITERRANEAN MIDDLE MIOCENE

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2002
The relative position of 30 main bioevents  pertaining to calcareous nannofossils and planktonic foraminifera was identified in the time interval between 13.75 Ma and 10.50 Ma, based on the quantitative study of the those microfossils in three ...

Polyphase Tectonic Evolution of the Puerto Rico‐Virgin Islands Microplate Revealed by Fault‐Slip Data and Stress Inversions

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract The northeastern Caribbean plate boundary (NCPB) includes the Puerto Rico‐Virgin Islands (PRVI) microplate that is bounded by oblique subduction zones in the Muertos and Puerto Rico Trenches, and by the Mona Rift, and the Anegada Passage rifts.

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

open access: yesThe Depositional Record, Volume 11, Issue 3, Page 954-974, June 2025.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

THE OSTRACODS IN THE PALAEOENVIRONMENTAL INTERPRETATION OF THE LATE LANGHIAN - EARLY SERRAVALLIAN SECTION OF RAS IL-PELLEGRIN (MALTA)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2002
The distribution of ostracods in the composed Langhian-Serravallian section of Ras il Pellegrin (Malta) has been studied quantitatively to define the evolution of both the assemblages and the palaeoenvironmental conditions.

Euryhaline preferences of the decapod crab Mioplax socialis enabled it to survive during the Badenian/Sarmatian extinction (Miocene) in the Central Paratethys

open access: yesGeologica Carpathica, 2016
Although decapod crustaceans of the Central Paratethys were diverse during the Badenian (Langhian-Early Serravallian), a dramatic drop in their diversity occurred at the boundary with the Sarmatian.

A new Middle Miocene selachian assemblage (Chondrichthyes, Elasmobranchii) from the Central Paratethys (Nyirád, Hungary): implications for temporal turnover and biogeography

open access: yesGeologica Carpathica, 2016
A new Middle Miocene (Langhian - early Serravallian) assemblage with shark and ray teeth from Nyirád (Hungary, Transdanubia, Veszprém County) consists of nine families, with 15 different species. The assemblage shares many common genera with other Middle

Facies and paleoenvironmental reconstruction of Early–Middle Miocene deposits in the north-west of the Zagros Basin, Iran

open access: yesGeologica Carpathica, 2019
Facies analysis and paleoenvironmental reconstruction of the Burdigalian to Langhian Asmari Formation, outcropping in the Khorram Abad Anticline, in the north-west of the Zagros Basin allow us to interpret the carbonate ramp history during the Early ...
