The principal goal of this study is to determine experimentally the solubility and diffusivity of Au, Cu and Mo in andesitic melt as well as the partitioning of these metals between silicate, sulfide/sulfate and fluid phases at typical magmatic conditions. The solubility/diffusivity and partitioning of metals or metal-bearing compounds (e.g., oxides, chlorides, sulfides etc.) will be determined as a function of volatile concentrations (H2O, Cl, S) in andesitic magma. The results are required for understanding and modeling natural processes related with the mobilization and transport of ore metals in magmatic systems. The data will be important for fundamental research as well as for economic purposes.

本研究的主要目的是通过实验确定安山岩熔体中Au、Cu和Mo的溶解度和扩散率，以及这些金属在典型岩浆条件下在硅酸盐、硫化物/硫酸盐和流体相之间的分配。金属或含金属化合物（如氧化物、氯化物、硫化物等）的溶解度/扩散性和分配将作为安山岩岩浆中挥发性浓度（H2O、Cl、S）的函数来确定。这些结果对于理解和模拟岩浆系统中与矿石金属的动员和运移有关的自然过程是必要的。这些数据对基础研究和经济研究都很重要。
