Abstract：Rare earth elements (REE)were analyzed by ICP-MS analysis in 138 surface sediments samples collected from in the eastern Bohai and northern Yellow Seas,China.The results indicated that the REE UCC normalization distribution pattern in surface sediments in the eastern Bohai and northern Yellow Seas was similar to that in Chinese loess,and also those of coastal rivers including the Yalu River,the Yellow River and other rivers ,indicating that the sediments in study area were mainly de-rived from the mainland substance.Provenance discrimination results showed that the sediments in the Shandong Peninsula and southwestern shore were mainly derived from the Yellow River,the area affected by the coastal current of the Shandong Penin-sula and near shore tidal current;REE composition characteristics of sediment in the eastern part in the study area were similar to the Yalu River sediments,indicating that the sediments of the eastern study area may be supplied by the Yalu River.Sedi-ments of the western part of the study area were mainly derived from the Yellow River and Liaoning coast material input,the local presence of the Luanhe River,Liuguhe River substance.The material of southeast in the study area mainly derived from the Yellow River.The REE contents and parameters of characteristic value were analyzed by the Q cluster analysis,the study area can be divided into four different regions,Namely region in the eastern part of the North Yellow Sea (Ⅰ),the Shandong Peninsula inshore surrounding area (Ⅱ),middle area in the eastern Bohai Sea (Ⅲ)and distributions in the northwest and southeast of the study area (Ⅳ).
