Barium isotopes in ocean island basalts as tracers of mantle processes
The compositions of ocean island basalts (OIB) can record signatures of ancient subducted
crust that has been recycled through the mantle. Based on their radiogenic isotope, major …

钡(Ba) 是大离子亲石碱土金属元素, 也是流体活动元素. Ba 在地幔熔融过程中高度不相容,
因此在地壳中含量远高于地幔. Ba 同位素在低温环境和流体作用下可发生显著的分馏 …
