The emphasis of this exploratory project is to conduct an experimental study of the partitioning of boron between muscovite and aqueous fluids. The experiments will involve the use of double-capsule techniques, with the run products being analyzed by isotope dilution. Run conditions for the study are 600, 800, and 1000oC at 2 GPa and at 800oC at 1,2 and 3 GPa. The techniques developed in this research and the partitioning results will ultimately find application in research related to the use of boron and its isotopes as geochemical tracers in subduction zone processes.

这个探索性项目的重点是进行一次 硼在铝合金中分配的实验研究 白云母和含水流体。 实验将涉及 采用双胶囊技术，配合润品 通过同位素稀释进行分析。 的运行条件 研究是在600、800和1000 ℃下2 GPa和在800 ℃下1、2 3 GPa。 这项研究中开发的技术和 分区结果最终将应用于 与硼及其同位素作为 俯冲带过程中的地球化学示踪剂。
