在陆地地质研究中,载体的稀土元素(Rareearthelements,简称REE)信息已被广泛应用于指示物质来源、岩石矿物的形成条件、地球化学分异作用及沉积环境变化等。相比之下,海洋中稀土元素的研究尚属一个薄弱环节,主要原因之一就是海水中REE含量太低(10-12g/L～10-15g/L),且海洋环境
In the study of terrestrial geology, the information of rare earth element (REE) has been widely used to indicate the source of the materials, the formation conditions of rock minerals, the geochemical differentiation and the changes of sedimentary environment. In contrast, the study of rare earth elements in the ocean is still a weak link, one of the main reasons is that the REE content in seawater is too low (10-12g / L ~ 10-15g / L), and the marine environment
