Abstract: Fortyfour sediment samples were collected from the Xiangjiang River and its tributary, and its REE concentrations were analyzed using Inductively Coupled PlasmaMass Spectrometry (ICPMS). The total REE concentration(∑REE), lightREE (LREE) and heavyREE concentration (HREE)were 63~387,58.2~353 and 4.8~34 mg·kg1, respectively. In spite of district differences in REE concentrations, the chondritenormalized REE patterns are characterized by LREErich right curves in the suspended matter of all samples. The REE curve normalized by North America shales(NASC) is a horizontal one. REE in suspended matter of Xiangjiang River are controlled by many kinds of factors, probably associated with clay minerals and heavy minerals. The chondritenormalized REE patterns in suspended matter of Laodao river displayed positive Eu anomaly, which is distinctly different from North America shales,and its sources and origin need to be further studied in the future.
