英文摘要	The aeolian dust is an integral component of the Earth surface system dynamics,participating in a range of physical,chemical and biogeological processes of the Earth system at various temporal and spatial scales.Especially,in the central Asia formed the large arid and semiarid areas,which is main source for the aeolian dust.The Asian dust cycle is one of the major dust systems on Earth,playing important roles in many processes and exerting impacts well beyond the region but the global scale.The thick aeolian dust deposits in the Chinese Loess Plateau(CLP)are considered to provide the best terrestrial record for the onset of Asian interior aridification and the evolutionary history of the Asian Monsoon.After more than 50 years'hard work in the CLP,brilliant achievements about the aeolian dust have been gotten not only through the geolical records but also the numerical modeling.However,large variability in the basal ages of aeolian deposits makes the aeolian dust depositional history and the controlling dynamics controversial.The large aeolian dust accumulation is the result of joint efforts by both sides of tectonic activities and the climate changes.The previous research focused on the climate changes much but it seem to fail to take into accout the fact that tectonics also play a key role in the process of produce and transport the aeolian dust,which is named" Dust Factory ".Here we present a preliminary hypothesis for the tectonic controls of aeolian dust deposition in the CLP by connecting the two main uplift events of the Tibetan Plateau and the regional tectonic events with the aeolian dust accumulation history.Regional tectonic events in the Ordos Block(the basement of the CLP)during the Late Cenozoic are less recognized as controlling aeolian dust accumulation by sculpting the surface landscape.The stable tectonic environment of the Ordos Block since the Late Miocene might have been the main controlling factor that enabled the wide deposition of the aeolian Red Clay after~8 Ma.At last but not least,the previous research have redefined the roles of the rivers and wind in the formation of CLP.Though the loess has an aeolian origin,the rivers also takes important part in transporting the detrital material as a near source for the aeolian dust.We demonstrate that the accumulation and preservation of aeolian deposits within the CLP is actually largely controlled by the regional tectonic environment,climatic factors and the results between accumulation and erosion.
