Plio-Pleistocene Dust Traps on Paleokarst Surfaces: A Case Study From the Carpathian Basin

Frontiers in Earth Science, 2020
Plio-Pleistocene silt/clay-rich deposits and paleo-karst fissure sediments from sites of the northern and southern parts of the Carpathian Basin were investigated.

Understanding the characteristics of loess strata and quaternary climate changes in Luochuan, Shaanxi Province, China, through core analysis

Open Geosciences, 2023
Profile sampling, which causes missing or overlapping horizons, has been generally used while studying loess stratigraphy and paleoclimate. Conversely, drill sampling of thick loess can provide a relatively complete and actual record of the Quaternary ...

Soils and terrestrial sediments on the seafloor: Refining archaeological paleoshoreline estimates and paleoenvironmental reconstruction off the California coast

Frontiers in Earth Science, 2022
On global, regional, and local scales, sea level histories and paleoshoreline reconstructions are critical to understanding the deep history of human adaptations in island and coastal settings.

Examining Local Climate Variability in the Late Pennsylvanian Through Paleosols: An Example from the Lower Conemaugh Group of Southeastern Ohio, USA

Geosciences, 2012
Three temporally close stratigraphic sections were excavated in Glenshaw Formation of Athens County, Ohio. The described units are Upper Pennsylvanian (Gzhelian, 305–302 Ma) and located in the distal portion of the Appalachian foreland basin.

Berriasian–Valanginian Geochronology and Carbon-Isotope Stratigraphy of the Yellow Cat Member, Cedar Mountain Formation, Eastern Utah, USA

Geosciences, 2023
The Early Cretaceous Yellow Cat Member of the terrestrial Cedar Mountain Formation in Utah, USA. has been interpreted as a “time-rich” unit because of its dinosaur fossils, prominent paleosols, and the results of preliminary chemostratigraphic and ...

Loess Strata Distribution Characteristics and Paleoclimate Spatial Pattern during the Last Interglacial in the Luohe River Basin

Geosciences, 2023
Paleoclimate studies of loess in China have focused mostly on the time series of a single borehole or profile. However, research on loess strata and regional paleoenvironmental patterns could facilitate a deeper understanding of loess as a ...

Xiashu Loess Deposits in the Lower Reaches of the Yangtze River and Their Paleoclimatic Significance

Redai dili, 2023
Quaternary Xiashu loess deposits are widely distributed in the middle and lower reaches of the Yangtze River. The Xiashu loess deposits provide an important archive for studying the area's paleoclimate. We analyzed the magnetic susceptibility of 239 bulk

Research on the relationship between saturated permeability and pore distribution characteristics of loess-paleosol

Shuiwen dizhi gongcheng dizhi
Due to differences in sedimentary environments, the paleosol is denser than the overlying loess, and its saturated permeability coefficients should be lower than that of the loess.

Dolomitic calcretes from the Changhsignian (Upper Permian) red beds of the Orenburg Cis-Urals, Russia

Учёные записки Казанского университета: Серия Естественные науки, 2021
The dolomitic calcrete profiles from the Boyevaya Gora and Tuyembetka sections, both represented by the uppermost Permian (Changhsignian) red continental deposits from the Orenburg Cis-Urals, were studied by sedimentological, mineralogical, and ...
