【摘要】：正中国大洋科学考察对中北太平洋的深海泥开展了系统调查,在中太平洋海盆新发现了稀土含量极高的深海沉积泥。最近,日本科学家在南鸟岛附近也发现了稀土含量接近7000×10~(-6)的富稀土泥(Ohta et al.,2016)。沉积泥样品显示稀土(REY)与P_2O_5含量良好的相关性,样品淋洗实验获得的磷酸盐溶液及其稀土特征,富稀土泥样品的稀土模式与海洋磷酸盐的稀土模式极其相似,以及从沉积泥中挑选出来的磷酸盐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.
