Abstract

The extent to which the mantle can melt depends on temperature, pressure, and its bulk composition. Reconstructing the extent of mantle melting from ancient primitive magmas or residual mantle peridotites can thus provide insights into the thermal and dynamic state of the Earth’s interior. Here, we show using compiled experimental data that olivine Forsterite (Fo = molar Mg/(Mg + Fe)) content in residual peridotites can be used to estimate melting degree:

校正橄榄石、橄榄石含量，以衡量残余橄榄岩的熔融程度

地幔可以融化的程度取决于温度、压力和它的整体组成。从古老的原始岩浆或残余的地幔橄榄岩中重建地幔融化的程度，从而可以深入了解地球内部的热和动态状态。在这里，我们使用汇编的实验数据表明，残余橄榄岩中的橄榄石Forsterite （Fo =摩尔Mg/(Mg + Fe)）含量可以用来估计熔融程度：
