The Variable Impact of Heinrich Events on the Benthic Environment of the Porcupine Abyssal Plain

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Heinrich events (HEs) are Pleistocene climate disturbances caused by massive freshwater discharges from the Laurentide Ice Sheet via the Hudson Strait. They appear in marine sediments as layers of ice‐rafted detritus (IRD) and significantly impact the benthic environment.

Type of Carbonate Production, Sedimentary and Tectonic Evolution of the Pliocene Mixed Carbonate Siliciclastic Unit (Macco) in the Tarquinia Basin, Central Italy

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
Piacenzian mixed carbonate‐siliciclastic succession (‘Macco’ unit) deposited on the passive margin of the Tyrrhenian back‐arc basin. Sedimentation was controlled by syn‐sedimentary tectonics, with NW–SE first‐order faults (3–4 km) creating accommodation space and NE–SW second‐order faults (~0.5 km) influencing facies distribution and growth structures.

Multi‐Proxy Thermal History of Basin Heating During Cordilleran Orogenesis in the Magallanes‐Austral Retroarc Foreland Basin, Patagonian Andes

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
Paleogene unconformity development from ~64 to 22 Ma for the Magallanes‐Austral retroarc foreland basin (MAB). Schematic shows (A) MAB foreland subsidence and basin infilling, (B) onset of cooling and basin inversion as subducting plate shallows, (C) continued foreland uplift, erosion and cooling as the oblique Farallon‐Phoenix ridge subducts beneath ...

The Celliforma ichnofacies in calcareous paleosols: An example from the late Miocene Cerro Azul Formation, La Pampa, Argentina [PDF]

open access: yes, 2016
Invertebrate trace fossils from the late Miocene Cerro Azul Formation (La Pampa, Argentina) are described and compared with known paleosol ichnofacies. The formation is a loess succession punctuated by numerous calcareous paleosols.

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Neoichnology of a Lake Margin in the Canadian Aspen Parkland Region, Cooking Lake, Alberta

open access: yesSedimentologika
Neoichnology provides insights essential for interpreting trace fossils in the rock record. Despite the wealth of studies conducted in marine nearshore environments, non-marine environments including lacustrine settings have received comparably little ...

Ichnological insights into deoxygenation across the Cenomanian–Turonian Boundary Oceanic Anoxic Event 2 in the northern extent of Western Interior Seaway (west‐central Alberta)

open access: yesSedimentology, Volume 73, Issue 2, Page 355-390, February 2026.
ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...

JURASSIC TRACE FOSSIL LOCALITIES OF ADYGEYA (RUSSIA): NEW GEOHERITAGE UNDER ANTHROPOGENIC PRESSURE

open access: yesZbornik Radova: Geografski institut "Jovan Cvijić", 2019
Geological heritage, and generally geoheritage, needs identification in the regions known for the modern progress in geological research, and the risks of its damage have to be documented.
