Many commercially valuable elements including platinum and gold are extracted from magmas into sulphide melts under some conditions whose nature is poorly understood. The proposed research will make the first reliable measurements of the factors controlling the ability of sulphide melts to extract a range of sulphur-loving elements from magmas. The results will not only aid the search for new deposits of precious metals, but will provide fundamental knowledge for use in such diverse disciplines as extractive metallurgy and planetary geochemistry.

许多有商业价值的元素，包括铂和金，在某些条件下从岩浆中提取到硫化物熔体中，其性质知之甚少。拟议中的研究将首次可靠地测量控制硫化物熔体从岩浆中提取一系列喜硫元素的能力的因素。研究结果不仅有助于寻找新的贵金属矿床，而且将为提取冶金和行星地球化学等不同学科提供基础知识。
