Rare earth element (REE) in the surface sediments from Pahang River (28 samples) and Kelantan River (22 samples) in the eastern portion of Malay Peninsula are analyzed to decipher the characteristics of REE composition and distribution, to discern the controlling factors of REE composition, and to illustrate the significances of provenance tracing of REE. The results show that the total REE ranges from 24.88 μg/g to 304.29 μg/g, with an average of 165.22 μg/g, for the Pahang River; and 126.02 μg/g to 281.40 μg/g, with an average of 181.15 μg/g, for the Kelantan River, respectively. The UCC standardization of REE indicates that Pahang River sediments enrich with heavy rare earth elements, in relative to light rare earth elements. However, there is no significant difference between light and heavy rare earth elements in the Kelantan River. The composition of source rocks and minerals plays a controlling role in the REE composition of the two rivers. The influence of chemical weathering in the Pahang River is greater than Kelantan River, and the difference of grain size among the Pahang River sediments leads to larger REE variations. δEuUCC-(Gd/Yb)UCC discrimination diagram demonstrates that it can be used as an effective index to qualitatively seperate the sediment source of two rivers. It can further be used to trace and identify the source of sediments quantitatively on the continental shelf of Malay Peninsula.
