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.

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

open access: yesThe 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.
