Aeolian origin and palaeoclimatic implications of the ?red clay? (north China) as evidenced by grain-size distribution

Loess Plateau storage of Northeastern Tibetan Plateau-derived Yellow River sediment

“…While some past research emphasizes aeolian transport from the Chinese northern deserts in formation of the Chinese Loess Plateau 31 32 33 34 35 36 , the evidence for this is also compatible with our conceptual model ( Figs 1 and 4 ). Loess grain size has a southward decreasing trend 34 , which is consistent both with a northern Chinese deserts or Yellow River source for the loess.…”

The vertical distribution of soil organic carbon and nitrogen in a permafrost‐affected wetland on the Qinghai–Tibet Plateau: Implications for Holocene development and environmental change

“…50 These parameters of the deposits in the MDX wetland profile (Figure 2c,d; Figure S1a,b) were roughly consistent with those of the eolian loess and red clay on the Loess Plateau. 50 These results indicate an eolian origin of parent material of the MDX wetland soils; that is, the parent material of the wetland soils is suggested to be loess.…”

“…The mean grain size, grain size frequency curve, cumulative frequency curve, and environmental discriminant parameter ( Y value) are usually used to determine the sedimentary facies of the deposits 50 . These parameters of the deposits in the MDX wetland profile (Figure 2c,d; Figure S1a,b) were roughly consistent with those of the eolian loess and red clay on the Loess Plateau 50 .…”

Miocene climate change on the Chinese Loess Plateau: Possible links to the growth of the northern Tibetan Plateau and global cooling

“…Two samples from the lowermost part consist of a sand fraction with a modal size around 300 lm, indicating strong transport dynamics linked to fluvial processes. Based upon sedimentological, geochemical, and geomorphological evidence [Lu et al, 2001;Vandenberghe et al, 2004;Guo et al, 2002;Qiang et al, 2011], most of the Red Clay deposits (<23.5 Ma) at Zhuanglang are considered to be of eolian origin.…”
