在岩浆熔体分异和结晶作用中,稀有元素的地球化学历史取决于两种主要的作用。在结晶分离过程中,稀有元素的大部分原子,在岩浆结晶时保留在岩浆岩中。只有小部分原子,由于同岩浆的挥发分形成化合物,可以与挥发组分一起在岩浆房中迁移 In magmatic melt differentiation and crystallization, the geochemical history of rare elements depends on two main roles. During the crystallization process, most of the atoms of the rare elements remain in the magmatic rocks during the crystallization of the magma. Only a small part of the atoms, due to the formation of compounds with the volatiles of the magma, can migrate with the volatile components in the magma chamber
