The geochemical role of iron in basaltic magmatism and planetary differentiation: an experimental study

原始陆地玄武岩中铁的含量变化惊人。 其原因是知之甚少，但可能包括熔融的富铁再受精地幔源，增加分区的FeO熔融深度，或氧化的一些FeO Fe2O3。实验研究Fe作为2+和3+对模型地幔物质部分熔融的影响，将有助于解决这个问题，同时也提供了校准上地幔相关系一般模型所需的基本热力学数据。

The amount of Fe in primitive terrestrial basalts is surprisingly variable. The reasons for this are poorly understood, but could include melting of Fe-enriched refertilized mantle sources, increasing partitioning of FeO into the melt with depth of melting, or oxidation of some FeO to Fe2O3. An experimental investigation of the effects of Fe both as 2+ and 3+ on the partial melting of model mantle material should help resolve this problem, while also providing the fundamental thermodynamic data needed to calibrate a general model for upper mantle phase relations.
