Depositional processes and stratigraphic evolution of the Campanian deltaic system of La Anita Formation, Austral-Magallanes Basin, Patagonia, Argentina [PDF]

open access: yes, 2019
Coastal depositional systems are commonly classified in terms of the relative interaction of wave, tide and fluvial processes. The La Anita Formation represents the opportunity to study and better understand coastal sedimentary systems.

Application of palynological data to the chronology of the Palaeogene lava fields of the British Province: implications for magmatic stratigraphy [PDF]

open access: yes, 1997
New high-precision ages, determined from palynomorph assemblages within intercalated sedimentary deposits, are presented for the Palaeogene lava fields (Skye, Mull and Antrim) of the British Province. These data reveal very rapid averaged eruption rates (

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

open access: yesThe 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.

Comparison of γ-ray spectrometry and ICP-MS methods for measuring radioactive heat-producing elements of rocks: a case study on borehole samples from the Sichuan Basin, China [PDF]

open access: yes, 2017
We compared the consistency of γ-ray spectrometry and inductively coupled plasma mass spectrometry by analyzing measurement results of the radioactive heat-producing elements U, Th, and K from borehole samples.

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

open access: yesThe 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.

The Western Irish Namurian Basin reassessed [PDF]

open access: yes, 2000
Current basin models for the Western Irish Namurian Basin (WINB) envisage an elongate trough along the line of the present-day Shannon Estuary that was infilled with clastic sediments derived from a hinterland that lay to the W or NW.

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

open access: yesThe 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

open access: yesThe 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.
