大洋玄武岩的研究表明，地幔是一个同位素非均质体，但这些非均质体的性质、分布和规模存在有问题。熔融物向表面的聚集、岩浆喷发前在岩浆房的混合作用可以使聚集前熔融体的化学和同位素特征变得模糊。橄榄石为主的熔融体包体的痕量元素和常量元素研究在确定聚集前熔融体...
Studies of the oceanic basalts show that the mantle is an isotopic heterogeneity, but there are problems with the nature, distribution and size of these heterogeneous bodies. The fusion of the melt to the surface and the mixing in the magma chamber prior to the magma eruption can obscure the chemical and isotopic characteristics of the melt prior to aggregation. Olivine-based melt inclusions in the trace elements and elements of the study to determine the aggregation before the melt ...
