Melting of the mantle can be investigated through experiments that simulate the conditions and the composition of the mantle. The basalts that erupt on the sea floor and the melts produced in experiments can be compared to imply the depth of melting, the amount of melting of the mantle and temperatures in the mantle. The principal investigator proposes to continue experiments with a new and innovative technique that has already been used successfully. These experiments will lead to a better understanding of melt generation in the mantle.

地幔的融化可以通过模拟地幔条件和成分的实验来研究。 海底喷发的玄武岩和实验中产生的熔体可以进行比较，从而暗示熔化的深度、地幔的熔化量和地幔的温度。 首席研究员建议继续使用已成功使用的创新技术进行实验。 这些实验将有助于更好地了解地幔中的熔体生成。
