“…The ESR signal intensity and crystallinity of fine-grained quartz indicate that the source region of loess on CLP is dominated by Badain Jaran Desert, Tengger Desert and the Gobi Desert [73]. Based on these lines of evidence, we may conclude that the loess on CLP is most likely to be derived from the arid lands between Qilian [37] and the modern dust in Yellow Sea [72]. Blue arrow indicated the silicate Nd-Sr isotopic composition of non-Ordos materials under different contribution of Ordos materials in the loess of CLP and the red curve showing the end-member mixing with equal steps [21]; the arrows in (b) are the directions of dust transport reconstructed by prevailing surface wind [2] and comparing the Nd-Sr isotope of loess and potential sources; the trajectories of Beijing dust storms are based on ref.…”

The North China and the neighbouring Mongolia in Asian Interior is characterized by extremely dry climate, resulted in one of the world's major dust emission centres. Deciphering the source region of Asian dust is critical for revealing the mechanism of the dust production, interpreting the paleo-environmental records of eolian deposits, predicting the overall environmental effects of dust, and setting the strategies for the control of contemporary dust storms. This paper summarizes the geochemical methods applied to the source tracing of Asian dust. Nd-Sr isotopes were the most extensively studied source tracer of Asian dust and have been successfully applied in many cases. Geochemistry of detrital monomineral shows great theoretical advantages in source tracing and deserves further studies. The short-range transportation of Chinese loess with direction similar to that of the prevailing near surface wind is revealed. Source tracing also shows that the Asian dust has two ultimate material sources from the northern margin of the Tibetan Plateau and the Central Asian Orogen, which confirms the importance of mountain processes in the production of silt eolian particles. Based on the recent progresses on the source tracing of Asian dust, discussions are expanded on the natural background of Asian dust storms and potential anthropogenic influence, the materials evolution of the source regions of Asian dust and its relationships with climate changes and Tibetan uplift, and the role of Tibetan uplift in the Asian dust system. desert, loess, Asian dust, dust storm, Tibetan Plateau Citation:Chen J, Li G J.

“…The silicate Nd-Sr isotopic composition of modern Asian dust [28,37,72,75,76] shows a large variation. Silicate Nd-Sr isotopes change greatly between dust events in the same place (Figure 12(b)), which is related to the difference in source region and transport pass way.…”

“…Figure 4 can be considered as an analogue to plots widely used in stable isotope studies, for example, εNd over 87 Sr/ 86 Sr (e.g. Nakai et al, 1993;Nakano et al, 2004;Lee et al, 2010). There was a significant positive linear correlation (r = 0.867) between 137 Cs content and the 137 Cs/ 90 Sr ratio in Mongolian soil samples because both of them are controlled by the amount of precipitation, as Igarashi et al (2009) assumed.…”
