英文摘要	The concentrations and distributions of trace metals and rare earth elements (REE) in sediment and mussel samples collected from the India Ocean hydrothermal area were analyzed. The metal correlation between organisms and sediments was investigated, and the ecological and chemical characteristics of REE were also explored. The results showed that, the trace metals in sediments were mainly Fe (96. 6 mg/kg), Mn (1. 14 mg/kg) and Zn (322. 6 mu g/kg), and Fe had high ratio of 98. 15% by normalized calculation, which indicated that the available sediments in this studying hydrothermal area mainly consisted of iron ore substances. Trace metals and REE distributions all had good correlation between deep-sea sediments and deep-sea mussels, and the correlation coefficients were 0. 991 for trace metals and 0. 996 for REE. The contents and distributions of metal elements in deep-sea mussels were different from those in offshore mussels. The REE distributions in sediments and mussels showed obvious fractionation phenomenon, and the enrichment of LREE in mussels was significant. Through the REE patterns, Eu and Gd in sediments and mussels all showed anomalies, and Eu had a significant abnormal phenomenon in deep-sea sediments and deep-sea mussels. Besides, delta(Eu) values were 9. 50, 10. 68 and 0. 23 in deep-sea sediments, deep-sea mussels and offshore mussels, respectively, and delta(Ce) were 2. 21, 2. 71 and 4. 38, which showed that the enrichment sources of REE in offshore mussels and deep-sea mussels were different, and the REE in sediments and mussels from the India Ocean were homologous.
