Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

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 ...

Distribution patterns of siltstone clasts in turbidites and their relation to grain fabric of host turbidites

Journal of the Sedimentological Society of Japan
Siltstone clasts are commonly known from turbidites in deep-water successions and have been interpreted to document information regarding depositional processes of host sandstones. Here we studied formative processes of siltstone clasts on the basis of size and fabric of siltstone clasts and of host sandstones.Although siltstone clasts generally ...

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...

Application of micro‐CT to resolve textural properties and assess primary sedimentary structures of deep‐marine sandstones

The Depositional Record
Over the past decade, there has been growing interest in the sedimentological community to use micro X‐ray computed tomography to analyse microfacies in sediment cores.

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Evaluating the Coupling Between Turbidites and Paleo-Earthquakes over 700 Years in the Southern Okinawa Trough, Taiwan

Geosciences
High-resolution marine sedimentary archives from active continental margins provide exceptional records of paleo-earthquake histories through the preservation of seismogenic turbidites.

Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

Tectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Event Deposits Recorded Over the Past 800 kyr in IODP Hole U1433A (South China Sea): Implications of a Revised Methodology for Chronology and Paleoclimate Reconstruction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Instantaneous event deposits such as turbidites, debrites, and slumps are common and frequently occur in marginal seas. These instantaneous deposits represent seconds to days in duration, and can therefore significantly impact age‐depth models and interpretation of paleoclimate history based on thick sedimentary sequences recovered in deep ...
