Tectonic Control of a Change in Sedimentary Environment at ~10 Ma in the Northeastern Tibetan Plateau

open access: yesGeophysical Research Letters, 2018
Tectonic uplift and climate change play a key role in the evolution of sedimentary systems in terrestrial basins. The Qaidam Basin in the northeastern Tibetan Plateau is well suited for studying these processes because of its location and its thick ...

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.

A comprehensive procedure for pollen extraction from bat guano deposits in organic and detrital matrices

open access: yesMethodsX, 2023
Although bat guano deposits have been proven to be excellent environmental archives for paleoecological and paleoclimate studies, the development of a standardized method specially catering to pollen extraction has received no attention so far.

Lake Pavin Sedimentary Environments [PDF]

open access: yes, 2016
In the recent years, Lake Pavin sedimentary basin has been intensively studied by several acoustic surveys (high resolution seismic reflection profiling, multibeam bathymetry) and gravity coring campaigns. This new data set combining acoustic images and multidisciplinary study of sediment cores allows characterizing contrasted subaquatic sedimentary ...
