Lateral sediment sources and knickzones as controls on spatio-temporal variations of sediment transport in an Alpine river [PDF]

open access: yes, 2013
Modern mixed alluvial-bedrock channels in mountainous areas provide natural laboratories for understanding the time scales at which coarse-grained material has been entrained and transported from their sources to the adjacent sedimentary sink, where ...

Environmental and climatic proxies for the Cañadón Asfalto and Neuquén basins (Patagonia, Argentina): review of middle to upper jurassic continental and near coastal sequences [PDF]

open access: yes, 2015
In this review, we include several proxies (sedimentology, palynology, invertebrates) from the Cañadón Asfalto and Neuquén basins, to infer the environments and regional climatic context during the Middle to Late Jurassic of Patagonia.

Fate of metals in coastal sediments of a Mediterranean flood-dominated system: An approach based on total and labile fractions [PDF]

open access: yes, 2011
The dynamics of sediment-bound metals (Cs, Cu, Ni, Pb, Ti and Zn) were studied off the Têt River (western Gulf of Lion), a typical Mediterranean coastal river punctuated by short and violent flash-floods.

The ichnofacies and ichnoassemblages in terrestrial deposits of China

open access: yesJournal of Palaeogeography, 2014
Over the last 30 years, terrestrial ichnofossil research was mostly focused on three ichnofacies: the Scoyenia ichnofacies, characterizing transitional fluvio-lacustrine environments, the Mermia ichnofacies, characterizing fully lacustrine settings, and ...

Color changes in yardang strata sediment in the Dunhuang Yardang National Geopark, Northwest China: Controlling factors and significance for sedimentary environments

open access: yesFrontiers in Earth Science, 2023
Introduction: Yardang stratum is the basic material unit of yardang landforms. Due to their protracted age and complex sedimentary structure, formative yardang stratum mechanisms remain poorly understood.

Provenance of sedimentary rocks [PDF]

open access: yes, 2009
Understanding the origins, or provenance, of a sedimentary deposit is an important aspect of geology. Sedimentary rocks are derived from the erosion of other rocks and thus provide important records of the geological environment at the time they were ...
