Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, From 40Ar/39Ar Dating and Fault Zone Morphology

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and

U-Pb geochronology of detrital zircon crystals from Caratas and Los Arroyos formations, Northeastern Venezuela.

Revista Técnica de la Facultad de Ingeniería, 2014
 LA-MC-ICPMS U-Pb geochronology in detrital zircons was performed in two Tertiary turbidite sequences from Northeastern Venezuela to contribute to the understanding of the Cenozoic history of the northern South America plate. The age results of detrital

Facies analysis provides new insights into event bed deposition in a hadal trench environment

Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

The origin of planar lamination in fine‐grained sediment deposited by subaqueous sediment gravity flows

The Depositional Record
Planar lamination is a ubiquitous component of modern and ancient fine‐grained sediments deposited by subaqueous sediment gravity flows. These sediments commonly exhibit alternating sub‐millimetre‐thick, sharply bounded silt‐rich and clay‐rich layers ...

Deformation of the Upper Oceanic Crust in the Outer Rise of the Sumatra Subduction Zone: Insights From P‐ and Doubly Converted S‐Wave Arrivals on Downward Continued Streamer Data

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The structure and properties of mature upper oceanic plates may evolve through mechanisms such as magmatism, hydrothermal circulation, and faulting. However, high‐resolution constraints, especially those involving both P‐ and S‐waves, remain scarce, limiting our ability to detect these processes and assess their impacts on crustal properties ...

Deltas: New paradigms

The Depositional Record
Deltas are deposits directly accumulated by land‐generated gravity flows in a standing body of water. The paradigm of deltaic sedimentation has dramatically changed during recent years, from the popular very simplified ternary models of marine littoral ...

FACIES AND ARCHITECTURE OF A SAND-RICH TURBIDITE SYSTEM IN AN EVOLVING COLLISIONAL-TRENCH BASIN: A CASE HISTORY FROM THE UPPER CRETACEOUS-PALAEOCENE GOTTERO SYSTEM (NW APENNINES)

Rivista Italiana di Paleontologia e Stratigrafia, 2019
This study documents the main depositional elements of a dynamically-controlled sand-rich deep-water turbidite system (Upper Cretaceous–Palaeocene Gottero system, north-west Italy).

Continental Growth and Recycling in Convergent Orogens with Large Turbidite Fans on Oceanic Crust

Geosciences, 2013
Convergent plate margins where large turbidite fans with slivers of oceanic basement are accreted to continents represent important sites of continental crustal growth and recycling.

Lateral variations in the signature of earthquake‐generated deposits in Lake Iznik, NW Turkey

The Depositional Record
Using lake‐sediment cores to document past seismicity requires a comprehensive understanding of possible lateral variations in depositional processes. This study aims to reveal the lateral variations in earthquake‐induced event deposits throughout Lake ...
