Distribution of the Platinum Group Elements Between Sulfide and Silicate Melts

首席研究员将研究某些 铂族元素（铱和钯）之间的硫化物 和硅酸盐熔体以及这种分布对 硫逸度、氧逸度和温度。平衡 实验将在高压（7-10帕）下进行。 在活塞缸装置中，以及在较低压力下， 立式管式炉结果将提供基本数据， 目前无法理解和解释铂族 元素地球化学，以及解决更普遍的问题 例如某些火成岩的演化。

The principal investigator will study the distribution of certain platinum group elements (iridium and palladium) between sulfide and silicate melts and dependencies of this distribution on sulfur fugacity, oxygen fugacity, and temperature. Equilibration experiments will be carried out at high pressure (7-10 kilobars) in piston cylinder apparatus, as well as at lower pressures in a vertical muffle tube furnace. Results will provide basic data, currently unavailable, to understand and interpret platinum group element geochemistry, as well as to address more general problems such as the evolution of certain kinds of igneous rocks.
