Experiments to quantify the geochemical behaviour of the precious metals

该项目旨在测量贵金属的高温地球化学性质，其中包括金、银和铂族元素。需要进行测量，以量化贵金属在硅酸盐熔体和金属或硫化物之间的分配，这将使其独特的地球化学特性能够应用于测试目前关于地球如何形成的假设，地球地幔随时间的组成，地球与月球的关系，以及岩浆系统形成铜金矿床的演变。由于新开发的实验和分析方法，避免了困扰以前尝试的问题，测量变得可行。

This project aims to measure the high-temperature geochemical properties of the precious metals, which include gold, silver and the platinum group elements. The measurements are needed to quantify the partitioning of the precious metals between silicate melts and metal or sulfide, which would enable their distinctive geochemical properties to be applied to the testing of current hypotheses on how Earth formed, the composition of Earth's mantle through time, the relationship of Earth to the Moon, and the evolution of magmatic systems to form copper-gold deposits. The measurements have become feasible due to newly developed experimental and analytical methods, which avoid the problems that have bedevilled previous attempts.
