| 英文摘要 | The REY-rich sediment from deep sea is a strategic resource. In order to determine geochemistry characteristic, origins and enrichment mechanism of REY-rich sediment, seawater and sediment samples were systematically collected from Western Pacific. We analyzed the major element, trace element and REY in sediment, as well as, REY in seawater. The redox condition, transfer and fractionation of REY and REY cycle of marine are used to analysis the origin of rare earth elements. The results indicated that, REY and Ce/Ce* show a negative correlation, and, biogenic P and Ca play a key role in REY-rich sediment. Systematic variations of Th/U, V/Sc, (La/Yb)(N), ( La/Sm)(N) and ( Sm/Yb)(N) values indicated oxic/dyoxic condition in sediment. The REE pattern showed HREE enrichment in bottom seawater, LREE and MREE enrichment in water-sediment interface, as well as, MREE and HREE enrichment in lower layer sediment. We suggested that, REY in sediment might come from seawater, and REY enrichment and negative anomalies of Ce was closely related with biological matter. The extensive oxic/dyoxic condition and biogenic oxide with relatively strong adsorption capacity resulted in few diffusion of sediment flux and enrichment of REY. |
