9406916沃森该项目涉及与深部地壳和上地幔化学过程有关的研究，重点是但不限于扩散。 该研究的五个关键子主题是：（1）下地壳和上地幔中流体和熔体的连通性，（2）岩浆中的扩散，特别关注硫，（3）矿物中的晶格扩散，使用卢瑟福背散射光谱（RBS）作为深度剖面工具，非常短，实验室诱导扩散梯度，（4）部分熔融地幔的渗透性，利用熔融碳酸钠代替玄武岩熔体的技术，（5）俯冲带中板片流体的化学输运，重点发展控制含水镁铁质组合中含水流体的脱挥发分、释放和捕获技术。

9406916 Watson This project involves research related to deep crustal and upper mantle chemical processes, focusing on but not limited to diffusion. Five key sub themes of the research are: (1) connectivity of fluids and melts in the lower crust and upper mantle, (2) diffusion in magmas, with specific focus on sulfur, (3) lattice diffusion in minerals, using Rutherford Backscattering Spectroscopy (RBS) as a tool for depth-profiling very short, laboratory induced diffusion gradients, (4) permeability of the partially molten mantle, using a technique in which molten Na-carbonate is substituted for basaltic melt, and (5) chemical transport by slab-derived fluids in subduction zones, focused on development of techniques for controlled devolatization, release, and capture of aqueous fluids from hydrous mafic assemblages.
