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.

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.
