The principal investigator will experimentally study aspects of fluids and melts in a reduced mantle. In particular, he will work on application of the sulfide oxybarometer to mantle phase assemblages, the determination of moissanite stability, the determination of CO solubility and speciation in sodium silicate melt, and the determination of the solubility of certain mineral assemblages in methane-bearing fluid at mantle pressures. All these studies have bearing on the redox state of the mantle at present and in the past, and on the development of the Earth as a whole over time.

首席研究员将通过实验研究简化地幔中流体和熔体的各个方面。具体而言，他将研究硫化物氧压计在地幔相组合中的应用、莫桑石稳定性的测定、硅酸钠熔体中CO溶解度和形态的测定，以及在地幔压力下某些矿物组合在含甲烷流体中的溶解度的测定。所有这些研究都与现在和过去地幔的氧化还原状态有关，也与地球作为一个整体的发展有关。
