Badenian-Pannonian (Langhian-Tortonian) evolution of the Blatné sub-basin, northwestern Danube Basin (Central Paratethys): integrated biostratigraphic, facies and seismic evidence from the Špačince-4 and Dubové-2 wells

open access: yesMineralia Slovaca
The Špačince-4 and Dubové-2 wells in the Blatné sub-basin of the Danube Basin were integrated with SP/RT logs and seismic profiles to refine Badenian–Pannonian (Langhian–Tortonian) stratigraphy and basin evolution.

Explainable Intelligent Framework for Reliable Drilling Rate Prediction and Feature Selection in Complex Sedimentary Formations

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT Accurate prediction of the drilling rate of penetration (ROP) is crucial to optimizing drilling performance, wellbore stability, enhancing operational efficiency, and reducing the overall cost of hydrocarbon exploration. This study focused on evaluating and comparing different machine learning models for ROP prediction and identifying the most

Late Neogene oroclinal bending in the central Taurides: A record of terminal eastward subduction in southern Turkey?

open access: yes, 2016
The Tauride fold-thrusts belt formed during ∼S–N convergence between Africa and Eurasia since Cretaceous time. The western end of the central Taurides strike NW–SE, highly obliquely to the overall convergence direction, and connect to the NE–SW ...

Vicariance and dispersal in the Aegean Archipelago: Molecular phylogeography reveals the origin and divergence times of Hydropsyche (Trichoptera: Hydropsychidae) species

open access: yesJournal of Systematics and Evolution, EarlyView.
Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.

Review and revision of Cenozoic tropical planktonic foraminiferal biostratigraphy and calibration to the Geomagnetic Polarity and Astronomical Time Scale [PDF]

open access: yes, 2010
Planktonic foraminifera are widely utilized for the biostratigraphy of Cretaceous and Cenozoic marine sediments and are a fundamental component of Cenozoic chronostratigraphy.

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope

open access: yesSedimentology, EarlyView.
ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

Integrating Phylogenomics and Biogeography of Spectracanthicus (Siluriformes: Loricariidae) Reveals Complex Evolutionary History in a Brazilian Shield Endemic Genus

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Loricariidae is the most diverse catfish family in the Neotropics. Within this group, the genus Spectracanthicus presents conflicting phylogenetic signals: morphological studies suggest monophyly, whereas previous molecular analyses often yield unresolved relationships and taxonomic uncertainty.
