From dust to dust: Quaternary wind erosion of the Mu Us Desert and Loess Plateau, China
The Ordos Basin of China encompasses the Mu Us Desert in the northwest and the Chinese Loess Plateau to the south and east. The boundary between the mostly internally drained Mu Us Desert and fluvially incised Loess Plateau is an erosional escarpment, up to 400 m in relief, composed of Quaternary loess. Linear ridges, with lengths of ~102–103 m, are formed in Cretaceous–Quaternary strata throug...
متن کاملMagnetic record of Mio-Pliocene red clay and Quaternary loess-paleosol sequence in the Chinese Loess Plateau
This article presents magnetic data of a 300-m-thick Mio-Pliocene red clay and Quaternary loess-paleosol sequence near Chaona town in the Central Chinese Loess Plateau. Detailed magnetostratigraphy shows that the aeolian red clay began to accumulate at ca. 8.1 Ma. Here, we presented a high-resolution rock magnetic data at 20-40 cm intervals within 4.5-8 ka span per sample of this section, which...

متن کاملThe Loess Plateau
The Loess Plateau (34°–40°N, 103°–114°E) is situated in the northern part of Central China (Fig. 2.1). It borders on North China Plain in the east, adjoins Qinghai-Tibet Plateau in the west, stands in the north of Qinling Mountains, and neighbors Inner Mongolia Plateau in the north. The Loess Plateau is a part of the dryland region in northwest China, with its altitude in the range of 800–3000 ...
متن کاملTetraether biomarker records from a loess-paleosol sequence in the western Chinese Loess Plateau
The ubiquitous occurrence of glycerol dialkyl glycerol tetraethers (GDGTs) in soils and their ability to record temperature and environmental changes offer the prospect of independently reconstructing continental paleotemperature and paleoenvironment from the loess-paleosol sequences (LPS) from the Chinese Loess Plateau (CLP). In this study we present records of GDGT-derived proxies for the las...
