Experiments to quantify the geochemical behaviour of the precious metals

点击翻译按钮获取中文摘要

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.
