This project aims to investigate and link the many studies of natural basalts to better understand Earth’s global tectonics and mineral resources. Much of our knowledge of the deep Earth’s history comes from studying the melting of the mantle to produce basaltic magma. This project will investigate experimentally at high temperatures and pressures, link studies of natural basalts with melting processes in simplified chemical systems. The expected outcome is a comprehensive model for the origin of basalts on Earth and in other rocky planets, which will establish the framework for the geochemical cycles of the elements and lead to a better understanding of mineral resources.

该项目旨在调查和联系天然玄武岩的许多研究，以更好地了解地球的全球构造和矿产资源。我们对地球深部历史的大部分了解都来自于研究地幔熔化产生玄武岩浆的过程。该项目将在高温和高压下进行实验研究，将天然玄武岩的研究与简化化学系统中的熔化过程联系起来。预期成果是建立一个地球和其他岩石行星玄武岩起源的综合模型，这将建立元素地球化学循环的框架，并导致更好地了解矿产资源。
