The chemical properties of magmas are the key to understanding igneous activity in the Earth, and hence the tectonic significance of magmatism, and the mineral resources resulting from past magmatism. The chemistry of magmas is also a determining factor in assessing the hazards associated with volcanic eruptions, including natural inputs into the atmosphere against which anthropogenic inputs causing climate change must be assessed. This research program will measure experimentally the way different magma compositions affect the solubilites of important volatile and trace-element components in magmas, providing the much-needed fundamental data to model magmatic activity.

岩浆的化学性质是理解地球上岩浆活动的关键，因此，岩浆活动的构造意义，以及过去岩浆活动产生的矿产资源。岩浆的化学性质也是评估与火山爆发有关的危害的一个决定性因素，包括评估造成气候变化的人为因素时必须对照的进入大气层的自然因素。该研究计划将通过实验测量不同岩浆成分影响岩浆中重要挥发性和微量元素组分可溶性的方式，为模拟岩浆活动提供急需的基础数据。
