The principal investigator will theoretically and experimentally study multi-component chemical diffusion in silicate melts. The primary goal is to derive and validate a model for multi-component diffusion in which the required quantities are self-diffusion coefficients and thermodynamic properties that can be obtained in separate experiments. Results of the research will have great importance in igneous petrology and will have wide application to processes occuring within the Earth.

主要研究人员将对硅酸盐熔体中的多组分化学扩散进行理论和实验研究。主要目标是推导和验证一个多组分扩散模型，其中所需的量是可以通过单独的实验获得的自扩散系数和热力学性质。这一研究成果将在火成岩岩石学中具有重要意义，并将广泛应用于地球内部发生的过程。
