SGER: Experimental Investigation of the Behavior of Boron in the Subducted Slab

该探索性项目的重点是对硼在白云母和水性流体之间的分配进行实验研究。 实验将涉及双胶囊技术的使用，并通过同位素稀释对运行产物进行分析。 该研究的运行条件为 2 GPa 下的 600、800 和 1000oC 以及 1,2 和 3 GPa 下的 800oC。 本研究开发的技术和划分结果最终将应用于与使用硼及其同位素作为俯冲带过程中的地球化学示踪剂相关的研究。

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.
