  • REE concentrations and distribution patterns in the different phases of water-sediment interface system at deep ocean floor were studied on the basis of samples of bottom water,sediments,interstitial water and polymetallic nodules collected from the East Pacific Basin by R/V Haiyaag 4 during HY4-871 and HY4-881 Cruises.It is suggested that RED concentrations in oxic interstitial water are lower than that in bottom water,REE contents of polymetallic nodules,except Ce,are similar to that of sediments.Bottom water,sediments and interstitial water are almost the same in REE distribution patterns.MREE enrichment relative to LREE and HREE and negative Ce anomalies,MREE enrichment has been found in polymetallic nodules,and Ce shows positive anomalies.REE contents in sediments increase with depth,and the variations of distribution patterns with depth have not been found.
