【摘要】：正中國大洋科學(xué)考察對中北太平洋的深海泥開展了系統(tǒng)調(diào)查,在中太平洋海盆新發(fā)現(xiàn)了稀土含量極高的深海沉積泥。最近,日本科學(xué)家在南鳥島附近也發(fā)現(xiàn)了稀土含量接近7000×10~(-6)的富稀土泥(Ohta et al.,2016)。沉積泥樣品顯示稀土(REY)與P_2O_5含量良好的相關(guān)性,樣品淋洗實驗獲得的磷酸鹽溶液及其稀土特征,富稀土泥樣品的稀土模式與海洋磷酸鹽的稀土模式極其相似,以及從沉積泥中挑選出來的磷酸鹽生物碎屑的富稀土含量和模
[Abstract]:A systematic investigation of deep-sea mud in the Central and North Pacific Ocean has been carried out during the China Oceanic Science Survey, and a new deep-sea sediment with extremely high rare earth content has been discovered in the Central Pacific basin. Japanese scientists also found the rich rare-earth mud Ohta et al.n2016 near Nanyao Island. The deposited mud samples show a good correlation with the content of P _ 2O _ 5. The phosphate solution obtained from the sample elution experiment and its rare earth characteristics are also found in Japanese scientists. The rare earth patterns of rare earth rich mud samples are very similar to those of marine phosphates, and the rare earth rich contents and modes of phosphate bioclasts selected from sedimentary mud are very similar to those of marine phosphate samples.
