Quantitative analysis of channel characteristics of distributive fluvial systems

Sedimentology, EarlyView.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, EarlyView.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, EarlyView.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.
