An Experimental Study of Fluids and Melts in a Reduced Mantle

首席研究员将对还原地幔中的流体和熔体进行实验研究。特别是，他将致力于硫化物氧压计在地幔相组合中的应用，碳硅石稳定性的测定，CO在硅酸钠熔体中的溶解度和形态的测定，以及某些矿物组合在地幔压力下在含甲烷流体中的溶解度的测定。所有这些研究都关系到现在和过去地幔的氧化还原状态，以及整个地球随时间的发展。

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.
