A four stage evolution of the White Channel gravel: Implications for stratigraphy and palaeoclimates [PDF]

, 2014
Although the White Channel gravel (WCG) of the Klondike district, Yukon, contains gold placers which have been exploited for over a century, few sedimentological studies have been undertaken.

Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

Journal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

Methods for seismic sedimentology and inversion using physics-driven convolutional model-based artificial intelligence

Frontiers in Earth Science
Seismic inversion is vital for reservoir characterization but faces significant challenges in complex fluvial-deltaic systems due to strong heterogeneity and thin-bedded formations.

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

The Jurassic of North-East Greenland: The fluviatile Bristol Elv Formation, a new Middle Jurassic lithostratigraphic unit from Traill Ø, North-East Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2004
A new lithostratigraphic unit, the Bristol Elv Formation, is erected in this paper. It is only known from Traill Ø, East Greenland, where it unconformably overlies Triassic redbeds of the Fleming Fjord Formation and is overlain by lithologically similar ...

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

Dynamics of fluvial fine sediment transfer in the River Esk, North Yorkshire, UK [PDF]

, 2006
A full understanding of the complexities of fluvial suspended sediment dynamics requires a holistic approach. The study presented here addresses fine sediment transfer in the River Esk catchment, which is suffering from the adverse effects of increased ...
