A continuous 500‐year sediment record of inundation by local and distant tsunamis in South‐Central Chile (40.1°S)

The Depositional Record, EarlyView.
Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

Sedimentary facies and architecture of mixed bioclastic‐siliciclastic deposits forming in an inferred strait environment: An example from the Early Pleistocene of Calabria, southern Italy

The Depositional Record, EarlyView.
Early Pleistocene mixed arenites and their associated conglomerates and sandstones were studied in detail in Calabria, southern Italy. This study suggests that the studied palaeo‐strait was not necessarily a wider and similarly oriented expression of the modern Strait of Messina.

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

The Depositional Record, EarlyView.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Ichnological discrimination of hemipelagic‐dominated slope versus basin‐floor mudstones: Insights from early Viséan successions of a distally steepened ramp, northern Iran

The Depositional Record, EarlyView.
This study integrates sedimentological and ichnological data to reveal the depositional processes and environmental conditions of deep‐water muddy gravity flows in the Mobarak Formation. It highlights distinct ichnocoenoses and bioturbation patterns, offering insights into basin‐floor versus slope mudstones and their implications for hydrocarbon ...

Controls on carbonate island formation and evolution: South Joulter Cay, Great Bahama Bank

The Depositional Record, EarlyView.
The evolution of South Joulter Cay occurs in three stages: linear ridges shaped by waves and longshore currents, arcuate ridges influenced by tidal currents and channels, and cuspate ridges formed by variable wind and wave directions. These processes are driven by climatic and oceanographic factors.

Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

The Depositional Record, EarlyView.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

Opposing shear senses in a subdetachment mylonite zone: Implications for core complex mechanics [PDF]

, 2010
[1] Global studies of metamorphic core complexes and low‐angle detachment faults have highlighted a fundamental problem: Since detachments excise crustal section, the relationship between the mylonitic rocks in their footwalls and the brittle deformation

Early impact basins and the onset of plate tectonics [PDF]

The fundamental crustal dichotomy of the Earth (high and low density crust) was established nearly 4 billion years ago. Therefore, subductable crust was concentrated at the surface of the Earth very early in its history, making possible an early onset ...

Horizontal mantle flow controls subduction dynamics [PDF]

, 2017
It is generally accepted that subduction is driven by downgoing-plate negative buoyancy. Yet plate age –the main control on buoyancy– exhibits little correlation with most of the present-day subduction velocities and slab dips. “West”-directed subduction

Cooling climate across last interglacial high stands on San Salvador and Great Inagua, The Bahamas

The Depositional Record, EarlyView.
Temperature data comparison with last interglacial mollusc clumped isotope data from this study, as well as from Bermuda (Minnebo et al., 2024; Zhang et al., 2021). The ‘later’ and ‘earlier’ ages within MIS 5e refer to Reef II and Reef I, respectively, for Bahamas data.
