Abstract The study of provenance of loess on the Chinese Loess Plateau is critical for revealing evolution patterns of atmospheric circulation in East Asia and the interaction between tectonics and climate evolvement. By now,numbers of studies on provenance of loess sediments have been carried out based on different tracing systems. However,the temporal and spatial variation of loess provenance and its dynamic mechanism have not been well understood. Based on the comprehensive review of the previous studies on the Chinese Loess Plateau,the provenance and possible changes of the Quaternary loess were analyzed from the perspective of factors affecting the composition of87Sr/86Sr and 143Nd/144Nd,and the U-Pb age spectrum of single grain detrital zircons. The following conclusions are obtained. (1)The variations of Sr-Nd isotopic compositions in loess during the Quaternary have exact geological significance,for the reason that the87Sr/86Sr in Quaternary loess changed significantly with a range of 0.002 580~0.004 949,which is beyond the influence of analysis error(<0.000 018)and the maximum radioactive decay effect(<0.000 026 during the 2.6 Ma period and<0.000 001 during a glacial-interglacial interval);the variation of 143Nd/144Nd(0.000 095~0.000 240)during the Quaternary is also beyond the influence of laboratory analysis(<0.000 010)and radioactive decay effect(<0.000 013). (2)The variations of87Sr/86Sr and 143Nd/144Nd both in bulk sediments and in the dominant grain-size fraction of loess sediments are of significance of provenance change because they are hard to be interpreted solely regards of climatic changes given the provenance of loess sediments is stable. (3)Relative to the Sr-Nd isotope tracer system,the tracing systems based on single-mineral or single-grain measurement(e.g., zircon U-Pb age)is robust in detecting variation of the loess sediment provenance. (4)A limited study of the provenance of the loess based on the detrital zircon U-Pb age spectrum reveals that the original provenance of the loess in the Chinese Loess Plateau may have undergone significant spatial and temporal differentiation in geological history. In particular,different sections reflect the changes of the main provenance of the loess before and after 1.2 Ma. It is indicated that the study of the temporal and spatial variation of loess provenance by zircon U-Pb age spectrum has great potential to reveal the coupling process and history of lithosphere,atmosphere and hydrosphere.
