Collaborative Research: Partial Melting of the Shallow Mantle from Thermodynamic Modeling of Mineral and Melts

海洋中脊之下地幔融化的区域永远不会被直接取样，因此了解地幔的融化取决于在熔融发生的温度和压力下的实验室实验。这些实验，加上地幔矿物的热力学，使我们能够预测融化的数量，融化的温度，以及海洋脊下融化的深度范围。然而，目前的预测与使用熔化率低于5%的技术进行的新熔化实验不一致。因此，似乎需要进行一些关键的实验和改进热力学模型。提出的工作是进行实验，并将新的热力学数据纳入现有的预测模型。

The region beneath mid-ocean ridges where the mantle melts will never be sampled directly, so understanding melting in the mantle depends on laboratory experiments at the temperatures and pressures where melting occurs. These experiments, coupled with thermodynamics of mantle minerals, have allowed us to predict the amount of melting, the temperature of melting, and the depth range of melting beneath ocean ridges. The present predictions, however, do not agree with new melting experiments using techniques that produce less than 5% melting. Thus, it appears that a few key experiments and refinements of the thermodynamic models are needed. The proposed work is to conduct the experiments and incorporate new thermodynamic data into existing predictive models.
