Mutually according concept for biostratigraphic data and clinoform model of western siberian tithonian-barremian deposits

Известия высших учебных заведений: Нефть и газ
There is a unique situation for past decades with Western Siberia Tithonian-Barremian deposit’s regional schemes: the clinoform model of their structure is generally accepted in regional oil exploring organizations, and at the same time, there exists ...

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Geochemical characteristics and hydrocarbon generation potential of lower cretaceous source rocks in the eastern peripheral basin group of the Songliao Basin, Northeastern China

Frontiers in Earth Science
IntroductionThe petroleum basin system in Northeast China is characterized by the Songliao Basin and its Mesozoic–Cenozoic peripheral small-to medium-sized basins. With escalating exploration challenges and operational costs in the mature Songliao Basin,

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.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Geophysical investigation at Sainte‐Marguerite‐sur‐Mer (Normandy, France): From a supposed landfill to a forgotten military network?

Near Surface Geophysics, EarlyView.
Abstract This study focuses on characterising a strong and unexpected anomaly observed during an electromagnetic induction (EMI) survey conducted on the chalk cliff plateau at Sainte‐Marguerite‐sur‐Mer, in the Normandy region, France. The site was selected for a long‐term study of chalk cliff coastal erosion that began in 2017 and has been studied for ...
