英文摘要	The geochemistry of rare earth elements (REE) in surface sediment from Cuarteron reef (N1), Johnson reef (N2), Hugh reef (N3), Gaven reef (N4), Fiery cross reef (N5), and Subi reef (N6) were firstly studied. The total REE abundance (Sigma REE) varied from 2.244 mu g.g(-1) to 21.661 mu g.g(-1), with an average of 4.667 mu g.g(-1). The LREE/HREE was from 2.747 to 9.869, with an average of 3.687, which indicated that the light REE was evidently enriched. Fractionation was observed between LREE and HREE. Gd with a negative anomaly was also detected in all of the stations. The negative anomalies of delta Eu from 0.11 to 0.25, with an average of 0.22, and the positive anomalies of delta Ce from 1.38 to 3.86, with an average of 1.63. The REE individual correlation values with Ca, Mn, Mg, Sr were r(ca) = -0.05, r(mn) = 026, r(Mg) = -0.14, and r(sr) = 0.08. (C) 2016 Elsevier Ltd. All rights reserved.
