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

原始陆生玄武岩中铁的含量变化惊人。其原因尚不清楚，但可能包括富铁的地幔源熔融，随着熔融深度的增加，FeO在熔体中的分配增加，或者一些FeO氧化为Fe2O3。对铁作为2+和3+对模型地幔物质部分熔融影响的实验研究将有助于解决这一问题，同时也为校准上地幔相关系的一般模型提供基本的热力学数据。

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.
