Holocene Slip Behavior and Shallow Structure of the Milun Fault at the Collision–Subduction Transition, Eastern Taiwan

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The Milun Fault forms the northernmost onshore segment of the Longitudinal Valley fault system, a plate‐boundary suture between the Eurasian and Philippine Sea plates in eastern Taiwan, and poses a significant seismic hazard to Hualien City. Despite destructive earthquakes in 1951 and 2018, the shallow structure, long‐term slip behavior, and ...

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Calcareous nannofossils of the Jurassic/Cretaceous boundary strata in the Puerto Escano section (southern Spain) — biostratigraphy and palaeoecology

open access: yesGeologica Carpathica, 2016
We obtained material from the Puerto Escano section (southern Spain) to study the Jurassic/Cretaceous (J/K) boundary interval. The same samples had already been processed for magnetostratigraphic studies and biostratigraphic zonation based on ...

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Serravallian (Miocene) nannofossils in Patagonia, Argentina [Nannofósiles del Serravalliano (Mioceno) en Patagonia, Argentina]

open access: yesCarnets de Géologie, 2009
For the first time, nannofossils found in the marine stratigraphic unit named "Patagoniano" which crops out at Cerro Chenque and Cerro Hermitte in southeastern Chubut, Argentina, are documented.

Palynology and nannofossil processing techniques

open access: yes, 1973
Techniques developed at the Atlantic Geoscience Centre are described. The procedures described permit the production of a large number of high quality preparations and should be useful to those responsible for establishing or maintaining palynological laboratory facilities.
