The 14 stable rare earth element (REE) concentrations and distribution patterns were investigated for surface waters (n=51), soils (n=52) and sediments (n=42) from the tropical Terengganu River basin, Malaysia. The chondrite normalized REE patterns of soils developed on four geological units showed enrichment of LREE, a pronounced negative Eu, and depletion of HREE with an enrichment order gran-ite>>metasedimentary>alluvium>volcanic. The REE patterns in sediments reflected the soil REE patterns with an overall order of abundance LREE>>MREE>HREE, however, positive Ce anomaly was either weak or absent in sediments. The chondrite normalized REE patterns for sediments also produced near-neighbor concentration anomalies (Eu-Gd-Tb). The dissolved ∑REE concentrations increased systematically in surface waters with distance from the upstream (
