YA01岩心沉积物中稀土元素总含量（ΣREE）在70 15 ~ 202 04μg/g之间。ΣREE的平均含量为155 18μg/g，接近大陆地壳沉积物中ΣREE平均含量的下限，略高于黄海和东海，低于渤海和南海。不同类型沉积物中稀土元素标准曲线变化趋势无差异，表明YA01岩心沉积物来源于同一物质来源。ΣREE、δEu和δCe具有明显的垂向变化，可能反映了岩性变化和沉积环境。Sm /Nd和Ce/La比值表明，沉积物来源接近黄河沉积物。
The total content of rare earth element(ΣREE)ranges from 70 15 to 202 04μg/g in sediments of core YA01.The average content of ΣREE is 155 18μg/g,approaching lower limit of the average content of ΣREE in sediments in the continental crust,and is slightly more than that of Yellow Sea and East China Sea,and less than that of Bohai Sea and South China Sea.The change trend of standard curves of REE has no difference in various types of sediments,which suggests that the sediments of core YA01 come from the same material source.ΣREE,δEu and δCe have obvious vertical changes,which may reflect lithologic change and sedimentary environment.Base on Sm /Nd and Ce/La ratios,the sediment source is near sediments from Yellow River.
