稀土元素的地球化学行为——在岩石中的原始丰度、分布的形式和方式、地质作用过程中迁移的规律性(分散和富集)——是由其原子结构和性质所决定的。
Geochemical behavior of rare earth elements - the original abundance in rocks, the form and pattern of distribution, the regularities of migration (dispersion and enrichment) during geological processes - are determined by their atomic structure and properties.
