Two-phase Himalayan extension recorded in the Late Miocene-Pleistocene Gyirong Basin, south Tibet

期刊: SEDIMENTARY GEOLOGY, 2021; 417 ()

The Late Miocene-Pleistocene Gyirong Basin in the central Himalaya provides a record of basin evolution in response to tectonic extension within the a......

The effect of diagenesis on rare earth element geochemistry of the Quaternary carbonates at an isolated coral atoll in the South China Sea

期刊: SEDIMENTARY GEOLOGY, 2021; 420 ()

The redox state of ancient seawater is crucial to understanding the variations in atmospheric and oceanic conditions in the geological past. Rare eart......

QGrain: An open-source and easy-to-use software for the comprehensive analysis of grain size distributions

期刊: SEDIMENTARY GEOLOGY, 2021; 423 ()

In the last hundred years, analyses of grain size have been widely performed, and numerous powerful tools have been published. The unmixing of grain s......

Wave and storm signals in a lacustrine succession and their relationship to paleowind direction (Tanan Depression, Mongolia, early Cretaceous)

期刊: SEDIMENTARY GEOLOGY, 2021; 419 ()

Existing fan-delta depositional models for lacustrine basins do not adequately address significant wave- and storm-related processes. However, in many......

Ediacaran-Ordovician landscape of eastern South China: Constraints from sedimentary indices and detrital zircon U-Pb-Hf isotopes from the southeastern margin of the Yangtze Block

期刊: SEDIMENTARY GEOLOGY, 2021; 416 ()

The paleogeographic landscape is an important clue to clarify the controversy on the paleoposition of South China within the supercontinental cycles. ......
