Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Parasitic gastropod bioerosion trace fossil on Cenomanian oysters from Le Mans, France and its ichnologic and taphonomic context [PDF]

open access: yesActa Palaeontologica Polonica, 2017
We describe and name Loxolenichnus stellatocinctus Breton and Wisshak igen. et isp. nov., a bioerosion trace fossil on an Upper Cenomanian oyster from Le Mans (France). This trace is attributed here to a parasitic gastropod.

Spectral Analysis of Carboniferous Rhythmites Indicates Tidal Modulation and Marine Connectivity in the Cumberland Basin (Joggins Formation, Atlantic Canada)

open access: yesBasin Research, Volume 38, Issue 6, November‐December 2026.
Statistically significant cyclicity preserved in Joggins Formation rhythmites is most consistent with tidal modulation. These findings provide new quantitative evidence that tidal energy propagated into the Cumberland Basin, supporting interpretations of marine connectivity during Late Carboniferous deposition.

Spatial and temporal evolution of a coastal erg margin: The Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, Volume 73, Issue 6, Page 2081-2119, October 2026.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

open access: yesSedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

open access: yesSedimentology, Volume 73, Issue 6, Page 2381-2416, October 2026.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Bioerosion in shell beds from the Pliocene Roussillon Basin, France: Implications for the (macro)bioerosion ichnofacies model [PDF]

open access: yes, 2007
The marine Pliocene at the locality of Nefiach (Roussillon Basin, SE France) includes several shell beds constituted by oysters and scallops that bear a diverse and abundant bioerosion trace fossil assemblage.

The ethological study of Glossifungites ichnofacies in the modern & Miocene Mahakam Delta, Indonesia

open access: yes, 2013
Although firm ground assemblages are well understood, the Glossifungites ichnofacies concept generates some debates amongst geologists (Gingras et al., 2000), because firm grounds represent intermediate gradational state between soft ground and hard ...
