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

The Depositional Record, Volume 11, Issue 5, Page 1563-1595, November 2025.
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 ...

Resolving allogenic forcings on shallow‐marine sedimentary archives of the Taiwan Western Foreland Basin

Sedimentology, Volume 72, Issue 6, Page 1755-1785, October 2025.
ABSTRACT An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation ...

Geological Screening for CO2 Storage in Deep Saline Aquifers in the Lower Mainland British Columbia (LMBC), Canada

Greenhouse Gases: Science and Technology, Volume 15, Issue 4, Page 432-448, August 2025.
ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three ...

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

Dynamic Mud Deposition Along the Fluvial–Tidal Transition Zone in the Waihou River, Aotearoa New Zealand

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 3, March 2025.
Abstract The fluvial–tidal transition zone (FTT) is a critical interface where complex interactions between river flow, tides, and sedimentation shape geomorphic systems and influence the dynamics of aquatic environments. However, few previous studies have integrated real‐time hydrodynamic data with sedimentary deposits.

Characterisation and Architecture of Subsurface Strata in the Whatcom Sub‐Basin, Georgia Basin, Canada and USA

Basin Research, Volume 37, Issue 2, March–April 2025.
In the Paleogene and with the docking of Siletzia on North America's western margin, the Georgia Basin transitioned from a forearc basin to a forearc depression, and this drove a major re‐organisation of depositional environments and paleodrainages in the region. ABSTRACT Outcrops of sedimentary strata that infill the Georgia Basin, Canada and USA have

Pedogenic continental red beds: How, why and when red? Redox geochemistry and quantitative colour analysis of the Old Red Sandstone, South Wales, UK

Sedimentology, Volume 72, Issue 2, Page 442-474, February 2025.
ABSTRACT Continental red beds are coloured by secondary Fe(III)‐oxy‐hydroxides (mainly hematite) which makes them excellent archives of ancient near‐surface redox conditions. However, colour is often treated as a subjective physical property, and opinions differ widely as to the environment and timing of colouration of the red beds. This study utilizes

Firmground ichnofacies recording high-frequency marine flooding events (Langhian transgression, Vallés-Penedés Basin, Spain)

Geologica Acta, 2005
The decapod burrow Spongeliomorpha sudolica occurs associated with transgressive firmgrounds in the transition between Aragonian continental red beds and Langhian marine units in some of the inner sectors of the Vallès-Penedès Basin.
